The Voopoo X217 Mod is a very nicely built and well-designed mod that is quite comfortable to hold in the hand. It's a simple oval-shaped symmetrical mod with a front facing screen and a centered 510 pin. There have been a few mods like this in 2018 and I've always been a fan of the design. It has a good weight to it as well, not very heavy but feels solid. It's not much bigger than a dual-18650 mod either. While many 21700 mods have hit the market in 2018 due to their new popularity, most have been single-cell, so it's nice to see another one come out with that battery configuration. The sides have black carbon fiber accents and the fire button and back have resin panels on them. There is also a programmable U-shaped LED strip on the front of the mod. The battery door is a standard bottom latch system we see on many mods these days. It worked well for me with no issues. The screen is a large and bright 1.3" color square shaped screen. It's a full color screen too, not just color text, and comes with 8 pre-programmed backgrounds including the default black one.
