problems

I have been interested in a robobrew for a while, but always held back as I heard people having this problem or that. I live in Japan, and the seller is not an official seller so there is no warranty to speak of. And if something did go wrong it would all be out of my pocket, parts and shipping...

any suggestions would be great to new guy to home brewing. Cooper sparkling age kit, last 2 batches stuck at 1020 and no matter how long I leave, hydrometer checked, tried different types of water, temp varies between 22-30c. Really annoying as I want bottle some beers!
