Something like the iTaste VV, but perhaps cheaper? Maybe like a Twist/Spinner equivalent of it but with square shape, my boyfriend recently got into vaping and I have 3 batteries that I use regularly and he is using my iTaste (my main) because he doesn't want to use a pink battery, which is my other 2. He likes the square shape but doesn't need all the bells and whistles like LED display and puff counter. Does this exist?
