It is crap but everything in stores in the US is crap too, and Temu crap is merely half the quality for a tenth the price

I used it once when I noticed a hammock underquilt - something I'd been looking for (it's basically a thermal layer for your hammock so your butt doesn't freeze at night). For context, these can cost from 50€ to several hundred.

It did all the stupid prize wheel things and offered the typical bs it usually does. However it made me an offer - buy 6 items and the underquilt will be included free. It didn't specify any prices or the typical "cheapest item is free", so I bought 6 of the cheapest things I could find (something like 50 hair ties for 0.50€, a pizza knife for 1€ etc).

I got the underquilt (and some random things) for ~6€ and, surprisingly, it works extremely well, even for quite cold weather!

Never used the app again, though. After the initial offers to get you hooked, the prices are usually worse than buying locally or just using AliExpress.
