I used to feel the same way, but had an opposite experience: bought a buggy cable and, since I could find no other way to contact customer service, left a negative (not insulting) review. Cust svc contacted me and sent me a replacement...which was a much more expensive cable which wasn't even yet advertised on their site. They then asked me to change my review. So I amended my review saying the new product which they'd sent me for free was OK but I had no idea if the old one worked.
Also their Type C chargers didn't work with a MacBook + accessory adaptor, which was only described in the reviews.
It's not like one bad experience has soured me on the whole company, but now I try to spread my purchases between them and Aukey (who has also had some Type C duds -- check Benson Leung's reviews before purchasing!)
