I wouldn't have bought one either. I was traveling, and I brought two mods with me. I forget to set the extra one upright because I was rushed. When I went over the pass at 7400' it blasted the juice out all over my little Sigelei Spark. When I got to my destination, that Spark was DOA. Now I'm 220 miles from home and only have one mod.
I went to a vape shop, to get a backup unit. All my other dual battery mods had long since died, and the only thing they had was the Alien w/ Baby Beast. So I bought that. I really wanted an IPV8 instead, although everything IPV that I've owned has since died.
In the cup holder, it bounces around and hits the buttons. In my pocket, same thing, although it doesn't fire. It would just be nice if it had a wattage lock. I don't vape at high wattage anyways.
It was nice though to drive home 3.5 hours and not have to charge a mod the whole time. Got home with about 75% battery capacity remaining. That was really nice.
I'm not worried about it blowing up in my pocket because the little coil in there at high wattage will basically melt, ending up with "No coil" message. That happened on the trip also, but I did bring 3 tanks with me. I might just have to make a special "Alien Stand" for the truck. Now that I'm home, it doesn't matter about the pocket thing. I'll just keep the Sig Spark on me while walking/riding around. It never changes any settings in pocket or rocking around in the cup holder.
A side note. After getting home, I disassembled the Spark and cleaned it with tooth paste and distilled water. I rinsed with distilled and set outside to dry for 30 minutes (it's hot outside). It came back to life, tough little buggers.
