For me the stock (coppervape) UTA2 was the most garbage rta for flavour I've ever owned, the GEM clone must surely be better that. I would like to try one of these out but at £29.99 I'd want a 510 pin that didn't need taping. I'm much better off with drippers, you get far more flavour for the money and you can buy authentics at non millionaire prices. Thanks for the review Vic, in-depth as usual.
