I won't use Aliexpress or Temu for several reasons. The main one being the prices are so low a workforce somewhere is being exploited. Then at these prices quality, returns possibilities, security, sustainability etc. all have to be questionable.
There's always a reason for things being cheap.
I use Temu for some of my specialist tools, after all that is where the British companies that sell them but then from, and then resell them for ten times what I pay. I just paid £9.75 for a pair of bibbed long cycling bottoms with an excellent pad in, I am guessing if I bought them from a UK supplier they would have been five times the price and from the same source.
