I have multiple Innokin products, I've put all of them thru hell and back, and they still work like the day I got them!! They're a good looking, high quality, well engineered/designed device that's stood up to everything I've put them thru. I haven't had any problems with Innokin whether it was the battery, the box, the tubes, tanks, coils, or tips. They've definitely got my business and I will continue to use them. Anyone that's asked me about vaping and wanted to get started I've pointed them toward the iTaste VV V3. The price may be a little higher than an eGo or a Spinner battery but it's worth it for the added options you get with the VV. Also I'm not sure if any other makers do it but I like the scratch stickers that come with Innokin products that allows you to check the Innokin web site to make sure that they are genuine.
