Good vape when it works. In the 18 months I have owned my hopper it has only worked for aprox 3 months with rest of the time being in transit or at the workshop awaiting repairs. You could not rely on this as your only vape.
I own one since Oct 16 and never had issues so despite all i read about it...only use it through water though and it does the job and well. This is for solo use, it gets hot of course and needs cleaning now and then but process is easy. Never gets me down i have to say.
Rip and run. Great unit for on the go. I've had It for around 3 years, still working like a champ. ( I am one of the luckier ones I believe). Depending on how much you vape, make sure to pick up a few batteries.
Super hard hitting, tiny portable with great effects. Flavor dies off fast, many users have problems with broken units and long return times, but mine has been running great for over a year!!
