I agree. I've had about 400 Amazon orders over the past 20 years, and as far as I can remember, with every single one the item was as described and with good quality. I think I've had 3 problems over the years (item didn't arrive; missing part; container of spices opened during shipping) that were accidental in nature, and they were easy to resolve (refund or replacement)
It does help to be a bit sceptical about some listings. For example, a webcam by "GREETBUAY" for $25 is probably not going to be of high quality. So I don't buy those kinds of things. But in cases where the nature of the item is that it's a single piece of plastic that just needs to be the right shape, I've bought them from sellers with bizarre machine-generated names and received exactly what I wanted.
