The product itself is really good, I've been using the same coil daily for over a month. Still works great! The only negetive is the size. If it were a little bigger I would definitely give it 5 stars!
Hands down worth the money I spent, be careful they are fragile… but work great and taste better than others I’ve tried so far around the same price and availability.
This thing is fantastic. The battery is plenty powerful enoug. it cools evenly. The battery will last at least 10 dabs with preheating and everything probably more. I highly recommend this.
