The Digiflavor Alarm V4 MTL RTA evaluation marks virgin region for me, although I’m cognizant of their items I’ve never ever utilized one, so I have no concept regarding what to anticipate.

Digiflavor is a Shenzen based maker that were developed back in 2016 by moms and dad business Geekvape, with the moto of “It’s time to make the world better” it wasn’t long prior to their initial Alarm MTL container struck the vape market.

In 2017 the Digiflavor Alarm 25 GTA, a devoted solitary coil MTL RTA was launched flaunting a 5ml juice ability. Customer John Summers was quite taken with it.

A year later on, our Laura-ann Citizen took us with the ins as well as outs of the Alarm 2 GTA. The minimized container ability was greater than made up for by an updated construct deck. This suggested even more space for a bigger coil – it was also feasible to attain a limiting straight lung vape.

In 2020 the Alarm 3 GTA made a visitor look as component of the Digiflavor Z1 SBS set. The side installed screws were dumped in favour of leading installed. This enhanced the construct procedure by making coil installment much easier.

It’s been claimed that Geekvape produced Digiflavor as a method of providing specifically for the MTL vaper.

The Digiflavor Alarm V4 MTL RTA absolutely galvanizes that ideological background by going cycle. It duplicates the exact same size, GTA design construct deck as well as 2 message style of the 5 years of age original.

What Can We Anticipate From the Digiflavor Alarm V4 MTL RTA?

It resembles the construct deck will certainly fit anything as much as a 3mm internal size coil.

So we shouldn’t always anticipate to be keeping up ultra reduced electrical power commonly related to MTL vaping, that’s the enjoyable of explore coil constructs.

The small yet well balanced honeycomb air movement framework developed right into the deck will certainly have an effect on cloud manufacturing.

It’s most likely to be enhanced rather if utilizing mini coils or sizes of around 2 – 2.5mm. So anticipate coil dimensions to have an influence.

The elevation of the container has actually been diminished over previous variations. Anticipate action doming as well as close distance of the coil to the drip pointer to raise as well as focus the flavour.

It’s been recommended in the past that earlier variations of the RTA have actually additionally had the ability to use a limiting straight lung vape.

Absolutely nothing of the style as well as construct top quality of this most recent offering would certainly recommend anything apart from a devoted MTL vaping item.

To start with there’s the extreme distinction in elevation. From the leading cap to the bottom of the deck the container gauges a plain 28.5mm.

That doesn’t make it much taller than my cherished OFRF Equipment RTA – my perpetuity preferred solitary coil MTL tool.

Digiflavor Alarm V4 MTL RTA Drip Tips

Choose from a selection of 2, as well as give thanks to vape paradise for that due to the fact that the extensive drip pointer is a total monstrosity.

At around 23mm in elevation it looks completely misplaced as well as does much to stain the appearances of the container.

Although there’s air movement adjustability, I couldn’t rather fathom out exactly how it functioned.

It wasn’t up until I got rid of the AFC ring that it made any kind of feeling.

There are a collection of “hidden” air movement ports that rest behind the control ring. They’re just the same dimension as well as agent of the Digiflavor Linear air movement framework.

As a polycarbonate it’s typically clear or brownish-yellow in colour with a high level of rigidness.

I’ve 2 problems with this container. Initially it does not have a lot of a watching home window as well as second of all it’s tough to determine simply just how much of the container has actually been filled up.

I’m compelled to scrunch up your eyes down the fill port to inspect the degrees. I couldn’t locate any kind of method of getting rid of the PEI for cleaning up either. So perhaps that ought to check out 3 problems lol.

Inside the Container

It’s even more an instance of tipped doming on the internal smokeshaft as well as perhaps a little much less than I was anticipating.

The device top quality below though is excellent as well as looks extremely high-end.

I’m not the very best as well as absolutely not one of the most patient considered that my vision is quickly failing me! lol

Initial points initially. Get rid of the deck from the container by loosening clockwise.

Loosen up both message screws to ensure that the coil legs have the ability to travel through the clamps.

Placement the coil legs with the clamps as well as thoroughly tighten up the message screws.

The coil requires to be resting straight over the air consumption as well as at an elevation of around 2mm off the deck.

Cut away the unwanted of coil leg as near to the sides of the construct deck as feasible. This will certainly prevent any kind of feasible shorting with call with the internal smokeshaft.

Ideally utilizing a devoted construct tab gradually completely dry pulse the coil. Make sure all locations are gotten rid of. If they linger attempt playing the coil surface area with an ideal device.

The coil requires to warm up equally from the centre in an outward direction.

Digiflavor Alarm V4 MTL RTA – Just How Does It Do?

Prior to we relocate onto flavour as well as cloud duplication I feel I need to discuss the consisted of coils.

They’re extremely soft as well as flexible that makes them susceptible to damages.

RTA MTL fused Clapton and Clapton included coils

As A Result Of this I had a problem attempting to mount them. It wasn’t assisted by the message clamp system as there was no chance of holding them in position. On several events the coil legs just drew cost-free.

When I ultimately did handle to safeguard them the degree of distortion had actually made them worthless. Any kind of efforts at aligning them showed unproductive.

Therefore I chose to utilize my very own MTL coil which was extra durable.

Don’t obtain me incorrect. It’s unusual for a supplier to be so charitable with coils yet they simply didn’t help this quick-tempered bugger!

Digiflavor Alarm V4 Flavour as well as Cloud Manufacturing

The coil utilized was a Wotofo integrated Clapton with an internal size of 2.5mm. It’s the tiniest coil I might locate yet was an excellent suitable for the construct deck.

I utilized Trouble Team Dessert Strawberry which had a crossbreed pure nicotine material. I paired it with the Voopoo Drag X Plus Pro performing at 20W.

With air movement broad open I did see a small level of disturbance yet no spit back to ensure that was a favorable begin, any kind of efforts at a limiting lung hit dropped on extremely un-vape like ground.

– That’s to state it triggered a couple of unpleasant coughing fits.

On this establishing the flavour was currently gleaming with great deals of clearness, strawberry notes were tidy as well as delicious.

I couldn’t also recommend this to be a ventilated MTL, it was simply a great beginning factor.

Various Other Air Flow Adjustments

I called the air movement to around mid limitation.

The container started making extra crackling audios yet once again the flavour stood up wonderfully well.

This setup basically offered the excellent MTL vape.

I had the ability to reuse even more of the vapour rather than it running away out right into the bordering air. It was both was light as well as slender, something any kind of changed cigarette smoker will certainly value.

So there was a accurate depiction of the draw from a cigarette. It had a mild throat kick on this electrical power setup yet vapour manufacturing still stayed very discreet.

When shutting the air movement even more the vape was a little also limited yet inadequate to place the vape set MTL vaper off.

I really felt the flavour beginning to come to be extra reduced although still excellent with the air conditioning representative pleasing the taste.

It would certainly additionally come to be a little bit on the rough side. I did see light throat inflammation regardless of the crossbreed pure nicotine material. The level of smoothness of an open air movement draw had actually absolutely been shed.

I would certainly suggest utilizing juice proportions of 50VG/50PG generally with the Digiflavor Alarm V4 MTL RTA, it’s flawlessly fit for the dimension of coils the construct deck provides for.

Simply for rate of interest worth I attempted a 70VG/30PG juice as well as it didn’t take wish for a horrible completely dry hit to singe the rear of the throat. I never ever find out!

Digiflavor Alarm V4 Air Flow Monitorings

The Digiflavor Alarm V4 MTL RTA supplies all the air movement alternatives you might request.

They vary from a somewhat ventilated draw that declines to go across over right into limiting lung region to the traditional MTL vape popular to any kind of just recently transformed cigarette smoker.

Among one of the most outstanding monitorings was the precision of change when utilizing the Straight design AFC ring. It’s been developed to excellence making it feasible to see air movement distinctions despite the tiniest of tweaks.

None of the air movement alternatives appeared to have excessive of an effect on flavour top quality either.

Undoubtedly there was some dilution at greater limitation yet already the vape was also limited to be of usage anyhow.


  • Compact style
  • Fantastic construct top quality – knurling, threading as well as machining
  • Outstanding flavour as well as cloud manufacturing
  • Flexible direct air movement functions an outright reward
  • No dripping


  • Trouble in safeguarding coil under message screws
  • Needing to get rid of the container from the mod to make air movement modifications
  • The extensive drip pointer (subjective)
  • The absence of a watching home window

Last Testimonial Judgment

As formerly discussed I had my reasonable share of problems setting up a coil on the construct deck. What usually takes 5 mins wound up taking control of half a hr.

All due to the fact that the message screws were stopping working to secure the coil down. To rub salt in the wound the soft gold layered level head screws were currently revealing indications of damage.

I assume grub screws with common message openings would certainly have functioned better.

Air flow change was difficult without getting rid of the container from the mod. I discovered this a large inconvenience due to the fact that I’m one for tinkering, as well as it actually shouldn’t be a point nowadays.

For a container that’s style so well I have no concept what Digiflavor were considering with the extensive drip pointer, it’s virtually farcical. Either that or I’m simply being the normal stick in the mud.

Digiflavor Alarm V4 MTL RTA – General Efficiency

What it inevitably boils down to is efficiency as well as the Digiflavor Alarm V4 RTA supplies by the vape tons.

It offers among one of the most gratifying MTL vapes I’ve experienced thus far in 2021. This results from the mix of air movement alternatives, regular flavour throughout those alternatives as well as incredibly well balanced vapour manufacturing.

The honeycomb consumption makes sure lots of regulated air movement circulation under the coil which rests nearby from the drip pointer itself. Incorporate this with some identify tweaking of the air movement control ring as well as we’re onto a victor as for flavour buildings are worried.

It’s except the brand-new vaper by any kind of stretch.

It’s for somebody that knows structure, as well as for those tired of attempting to resource supply coils for their favored MTL container.

Most Importantly it’s for anybody that longs for uniformity to their flavour throughout a wide range of mouth to lung air movement alternatives.

So is it much better than my cherished OFRF Equipment RTA? Hmmmmm…

The exceptional flavour top qualities are matched to be truthful, buthe Digiflavor Alarm MTL RTA wins when it concerns construct top quality.

Digiflavor supply thrills with this one.
