There has been alot of talk about the spinner but the one I had started to have problems after about 60 days. Ive always loved the joyetech twist but some friends insist the spinner is better. There main point is that you can see the dial better which doesnt matter to me. joyetech i like cause its soild for ego batteries,. They dont break and they last long.If I was to buy a new battery which one should I get and why?
