Never ask people on this forum for an opinion. You can end up with 1000 different ones. You need to make up your own mind. I have 5 VTC minis and love them. If it goes dead, put another battery in and you are ready to go. That said, I used innokin products for the first 1.5 years that I vaped. Solid as a rock. If you decide to buy innokin, you will need to have 2 of them so that you can use one while the other is charging. You really can't go wrong with either of them.
