I thought I would share an update on this device after having abused it for the last couple of months....lol. The SMOKtech VV Gripper has been a great mod and creates clouds of vapor similar to the Vmax I had for a while, however there are some cons to this mod. The first issue is the battery door, my tab cracked in the first week of normal use with no accidents. But, then I dropped it several times on the hard wood floor and on some asphalt and that broke the door permanently. I now use a rubber band wrapped around my mod to hold the door shut.
Then I drop kicked my gripper on accident while walking to work. It bounced off of a parked car and landed in the gutter, in pieces.
So, I tore the case all the way apart, it was glued together, and reseated all the components. Then I used electrical tape to hold the case together, that was all I had at work. So now it is a Frankenstein of a mod but still hits like a train....lol.
So, the mod is not well built but cheap. I am glad I bought this instead of a more expensive mod. I am glad it is built the way it is as it allows for repair. I figure if I beat the case up too much, I can put the guts in something else and keep on vaping.
I have had more spendy mods that have lasted longer but like this cheap plastic box the best, go figure. I have super glued and broken the 510 connector loose several times.....lol. But for the price, this is the best mod for me to abuse and rebuild as needed. Just wanted to share my experience. Thanks for listening.
Using EH 2000mAH button top batts from madvapes and they fit fine and last a couple of days. Also the vivi nova tank with my own wrapped coils at various ohms works great. As well as the mini vivi.
