I’ve used Temu a few times. Most everything I’ve purchased have been legit. A lot of it is exactly the same as you’d get from Amazon for a fraction of the price. Even the photo of the products are the same.

I’ve even bought automotive accessories from them - cup holder insert from US based retailers $20. Temu <$5. Windshield sunshade from Amazon $17-27. Temu - $6. Exact same product.

I’ve had a problem with two things I got from them - an AirPod knock off that fell and broke and a set of two PD chargers that turned out to not be what they said they were - refunds for both were issued almost immediately.

Other small items like funny keychains, pens, pins and other small items bought as gifts for my employees, have been big hits.

My girlfriend wanted some anti fatigue mats for the kitchen. She found some and picked some out and had them in her list on Amazon. They want in sale one day ($33 or something like that I think) and before I ordered them I checked Temu - $9. Same product photos and everything. They’ve been great.

You just have to be careful what you get. Some things have been more expensive through Temu, so bonus in faster shipping from elsewhere. I’ve received orders in 7 days or as long as 14 days once. But typically 10-11 days.
