I only buy Nano-Tech's now, for the extra money it's worth it IMO.
I have had bad luck with mine as well. When they work properly, they are very good. I had one develop a "bump" in it. I had one 4S puff on a hot day. I had one 2S that arrived in the mail already puffed out of the case. My new 4S has trouble balancing one of the cells so it takes forever to balance charge. So, I am souring on them rather quickly.
Just for the record, I take good care of my lipos.
