Top site, I'd highly recommend it.
I've been using Aliexpress for over 6 months and have ordered 50+ items over many transactions and with various sellers. Out of the 57 items I've purchased, 4 resulted in disputes being opened by me for various reasons and 1 was cancelled by Aliexpress themselves as they suspected suspicious seller activity. On each occasion I was promptly refunded my money.
If you don't mind waiting a few weeks for the goods then you'll love it. It's a top site imho and I'll be shopping on there for many years to come.
