There will be a couple of good reviews but if the bad ones outweight the good, that's not positive. When things come from China, you may have the following problems:
1) You may not get what you ordered at all, and since it's based in China, you won't be able to do much about it except to contact your credit card company and deal with the hassle of getting your money back.
2) You may get the wrong thing and then you'll need to pay for the shipping back to China, which isn't cheap. Once you return it, there isn't a guarantee you'll get your money back or a new thing.
Basically you may be more likely to have problems. You also don't want to give credit card info out to a company that you don't know.
