After some time, I decided to make the transition from the Geekvape Aegis Solo 100w to something newer and ended up with the z80. The mod is decent overall (good power, easy menu, etc.) and very nice-looking. However, its positives end there. I use it with an MTL RTA atomizer. Let's start with the negatives:
-The build quality is mediocre, at least compared to my previous mod (which is now cheaper). The color easily fades and overall, when you hold it in your hand, it feels a bit cheap.
-The screen is nice, but the plastic on the front gets dirty easily from your hands and the screen becomes blurry. It needs constant cleaning if you want a clear view. Personally, I would prefer if it was made of glass.
-The soft grip it has (I have the leather one) is nice, but it doesn't make a noticeable difference when you hold it. You have to press it to realize that it's soft. It's a neutral characteristic.
-The atomizer doesn't sit completely flat when screwed on due to the curves of the mod. Personally, it bothers me in terms of appearance.
-The different modes it supposedly has are useless. You don't notice any difference in vapor or resistance life.
-The fire button rotates around itself and isn't stable in its position. It has a bit of space around it and "plays" when you touch it.
-Also, the fire button is pressed too easily, resulting in unintentional presses when it's in your pocket or simply when you hold it, causing the coils to burn.
-Lastly, and the WORST of all, it drains the battery like crazy. With my previous mod, I could easily go a day, but this one leaves me with half a day of battery life. It's completely tragic.

All of this comes from a vaper who has been involved in the hobby for 8 years. Personally, I wouldn't buy it if I had the chance. It's a waste of money. I'll probably go back to my old mod. It's a huge disappointment from a company whose products I used to enjoy a lot. Such a shame, Innokin.
