All of the reviews I can find online seem to be positive. (It's easy enough for a dodgy company to make up positive reviews but it's far harder for them to prevent negative ones).
Qwerkity is long-established; they used to trade as Presentsformen.co.uk, gaining praise for their customer service when things went wrong:

(That contrasts sharply with the comments about customer service, or the lack of it, from EasyLife:

I'd be happy to order from Qwerkity.
