Honest review time: Digiflavor Ubox kit

Here’s a look at a kit that came out about midway through last year but as far as I could tell didn’t get a whole lot of attention. It’s a deceptively simple kit made by Digiflavor a company probably best known for their rebuildable tanks and RDAs such as the Pharaoh a collaboration project made famous by the one and only RipTrippers. There really isn’t much to it so this one will be short and sweet. Here are my honest thoughts on the Digiflavor Ubox kit sent over from Buybest.com.

The Ubox Mod:

The ubox mod is incredibly simple and really only features three blue LED lights and a button. It contains a 1700mAh internal battery with a max power of 28W and max voltage of 4.2V. It’s also incredibly compact at only 60mm tall, 38.5m long and 24mm wide. At the top it’s got a slightly recessed 510 connection that appears to be made of stainless steel. The recess it sits in fits the included Utank Atomizer perfectly with just enough room to allow you to still turn the airflow control ring on the tank. The included tank is 22mm in diameter so anything bigger than that likely won’t fit on the device. On each side it’s got some textured surfaces to aid with grip and on the bottom of the device there are some venting holes should anything go wrong with the battery.

Down the face of the mod it sports a nice round clicky fire button that doesn’t rattle and feels good when pressed. It uses the standard five clicks to turn it on and off as well as a single press to fire the device. It also includes the most baic of safety protections like over heat and overtime protection which uses the same three lights to indicate whether there’s a problem or not. No other functions are included just basic power mode which as mentioned above is limited to 28w. Just below the fire button is the three LED lights which are used to indicate firing, charging as well as remaining battery life. Three lights obviously indicates a full battery and with each light extinguished it gets closer to an empty battery. I found when it got down to one light there was a significant drop off in performance and at that point I essentially needed to recharge. It did however seem to last quite a while on the first two lights before draining that low. Aside from these basic features the mod really doesn’t have much else to offer, just a simple straight forward direct from battery mod.

The tank:

The tank that comes with the kit is called the Utank and admittedly it feels a bit dates right out of the box. Granted this kit was released some time last year it already feel a bit behind when it comes to features. At the top it’s got a proprietary drip sleeve like we’ve seen on numerous other tanks. It’s comfortable enough but doesn’t leave many options if you don’t like the feel of it on your lips. Just below that is the top fill which basically opens the full top of the tank exposing the coil and glass for refilling. It works just fine but considering most others have now moved to slide open tops it feels just a bit dated. The tank is 22mm in diameter, stands 35mm tall and holds just 2ml of liquid. Airflow comes from the bottom and is adjustable via the sliding airflow control ring. It slides all the way around with no stops at either end and no clicks to hold it in place but it is fairly stiff so shouldn’t move around too much. It’s not really suited for mouth to lung vaping as even when closed down nearly all the way the draw is fairly loose and the included proprietary drip tip isn’t exactly conducive to MTL vaping.

The tank breaks down in to three pieces not including the tip sleeve or coil for easy cleaning or replacing the glass but no spare glass is included in the kit. The glass stays firm on the bottom part of the tank when opened for filling but can be removed for replacing the coil. Speaking of which it tends to be a slightly messy affair changing coils in tanks like this unless you drain it completely empty, even then having to unscrew the old coil will require some tissue. It’s not a big deal as most tanks out there still require a bit of a mess when swapping coils but it needs to be mentioned. On the very bottom of the tank it’s got some basic branding and a non adjustable floating 510 pin. It does protrude a bit but I wouldn’t recommend using any subohm tanks on a hybrid device.

The Coils:

The coils might be the most dated part of the tank and remind me a lot of old Atlantis style coils with threading on the top and bottom of the coil which acts to hold the tank together when assembled. It comes with two coils and both are rated at 0.5ohm and 20-30W which is pretty much ideal with the 28w mod it comes with. Performance from the coil was surprisingly good though and it produced satisfying flavour and a decent amount of vapour. The first pull if left sitting often required a bit of ramp up but beyond that it performed just fine. Break in time was minimal and I barely got any odd cotton taste after filling it up the first time. I do of course prime my coils and let them sit but after that it was pretty much good to go. I did find if chain vaping the tank would get a bit warm and the coil was just barely able to keep up but vaping at a regular pace never seemed to cause any concern. Coil life will ultimately depend on juice used, personal vaping habits and of course QC on the coils themselves but so far with the two included coils I’ve managed to get nearly three week on the first coil and I’m about two week into the second one so longevity should be fairly decent.


  • Compact size
  • Decent performance
  • Decent flavour and vapour
  • Super simple


  • Feels a bit dated
  • Struggles a bit with chain vaping
  • Not really suited for MTL vaping


I’ve got to admit I was a bit surprised by this little kit. I really didn’t expect much going in to it but came away realizing how simple a kit can be yet still be effective. The Ubox kit is definitely simple but functional and provides an overall decent experience. I personally think it would be best for new users looking for a simple yet reliable subohm setup that won’t break the bank but still provides a satisfying experience. Most seasoned vapers will probably pass on this one but even then it wouldn’t be bad as a worry free secondary setup for on the go vaping. So big thanks to Buybest for setting me up with the kit, it was a real eye opener!!
