VT Inbox styling and build quality

The VT Inbox features a compact box like design. It is made entirely from Zinc Alloy and it has a nice amount of weight to it but is still comfortable to use regularly. In my opinion the construction is really good and the device feels quite robust.

The 510 pin is solid and has a nice amount of travel to it. I had no issues getting the included Maze V2 RDA to sit flush. Keep in mind that while the device is intended as a Squonker it can of course be used with other atomizers. My Kayfun Prime was a good fit, as was my Hadaly RDA.

The side panels are magnetic and can be replaced with other styles, providing you’re willing to pay for them. On the model I received the panels featured a striking hologram style carbon fibre finish which I felt was highly complementary. Removing the front panel reveals the battery compartment and the juice bottle. The bottle has an 8ml capacity and features a lovely soft plastic which makes it very easy to squeeze. Fitting the bottle to the squonk tube is straightforward, but keep in mind to make sure the bottle is completely pushed inside or you can have a problem fitting the front panel. Like most things of this nature it just takes a little getting used to.

The only minor issue I could find was that the battery door did have some slight play/wobble and this can lead to some rattle on occasion, but it likely won’t bother you unless you’re extremely OCD. Nevertheless it was a bit of a let-down considering the device’s excellent construction.

The battery compartment was well laid out and there are clear markings showing correct battery orientation. Suitable venting is provide for in the base of the device. When you want to charge the battery you can either do it externally or make use of the included Micro USB Cable, which is also required for connection to the EScribe software. The port is sensibly located directly below the two adjustment buttons.

All of the buttons were well fitted and responsive. The LCD screen featured all of the typical information you would expect and can be further customized to suit the user by making use of EScribe. The display was easy to read and well lit.

The included Maze V2 RDA was certainly a bit of an oddity since it features a hinged top cap which is not really needed on a bottom fed atomizer. On the positive side of things it is fitted with a bottom fed pin and includes the standard 510 pin too. The construction on the whole was very good but the top lid did feel a bit loose on occasion. The Maze V2’s greatest advantage is the deck which features the ever popular two post Velocity style design which makes it extremely accessible to a newcomer.

Ease of use

Filling up the bottle and attach the feed tube is really straightforward, just keep in mind that the bottle needs to be pushed all the way into the compartment or you won’t be able to fit the door properly. I filled up the bottle with some Manabush Coyote Coconut. The Maze can be set up with either a single or dual coil and was a breeze to work with. I went for a 26 gauge dual coil which had a final Resistance of 0.5ohm. I then wicked both coils with Japanese cotton.


To begin with I used the VT Inbox in Variable Wattage Mode and I encountered no issues at all. The squonk action worked extremely well and the Maze V2 filled evenly with juice while squeezing the bottle and then drained away once I stopped. Flavour was very good, as was vapour production and while I personally preferred using my Hadaly I could find no fault with the Maze V2.

Speaking of my Hadaly, I then decided to fit it with a Stainless Steel coil to test out the device’s Temperature Control Mode. I had to adjust the Temperature a bit to suit my own preference but once I found the sweet spot I got excellent flavour, vapour and just the right amount of heat. I encountered no weird Resistance jumping at all in the short time I spent with the device.

Battery life was typical of a single 18650 but high settings, excessive use and Temperature Control will obviously drain it much faster


My only issue with this device is a small one and that’s the door. It isn’t that big a deal but I feel it lets down the overall high standard of the package down slightly. Yet despite that this product succeeds where it matters! The included RDA is a nice bonus and simple to work with, the Evolv chipset cannot be faulted and the squonking action was spot on.
