I mostly buy parts for my woodworking shop at home from Ali. A benchdog is a benchdog and they are absolutely the same to what you get at Amazon,etc. And they are literally 1/3 of the price here even if you add shipping and customs. So if one is truely shit I couldn’t care less.
So far I had no bad experiences really - one shipment was missing a 2 bucks piece but I can live with that. Some things actually surprised me as the quality I got was better than expected.
Electronic wise I bought a Qotom mini PC from them years ago (directly from the Qotom shop) which still works as my UTM.
