Honestly I never ordered from temu before But I lately bought tons of stuff from them for my parrot and I find it to be cheap and the quality in general is good. Sometimes I find same stuff in pet store on it but cheaper
You need to be careful where you get your supplies from for birds. They are much more susceptible healthwise to chemicals and Plastics and what things are actually made from. Even the kind of paint that is put on bars of cages is questionable. Believe it or not some of them still contain lead and most of them come from China. I've have 2 parrots for almost 30 years. For myself it has pretty much been a standing rule that I do not get anything from China for them. China does not really care what's in their products. Parrots are far more delicate than most animals when it comes to contamination.
I’ve bought bird stuff from there once when every place stopped selling the double sided sandpaper bird perches that my birds love, but the quality was not the same. The fixtures to attach them to the cage were all messed up, and they weren’t double sided. I found one seller on Amazon that had like a 12 pack for pretty expensive compared to other places, so I ordered those and they weren’t double sided either 😖 I’ve bought lots of bird toys from SHEIN. Like Ferris wheels and shopping carts and they go through those toys where they pull out shredded paper pretty quick, so I always get the multi packs for a good price on there
