I offer my tips. After I was taken by too many US brands made in China (Oster, Black and Decker, others) I did the following:

1. Look up the product owner manual. If you cannot find it on the mfr's site, skip the product.
2. Once you find the manual, read it over. Look for how or where to get replacement parts, that's a dead giveaway. If you see that parts orders come from China in 3 to 6 weeks, skip it.

Examples: I bought a well-rated (according to fake reviews) toaster oven. Had not done a user manual lookup beforehand. After ruining the inside tray in an accident a few weeks later, I did a search to buy a replacement tray. Not available! Also, no other parts available. Also, phony claim of serving as a convection oven. Controls are marked with a fan labeled 'turbo'. Out of curiosity I opened the chassis. NO FAN. I noted all this in an online review. They removed the review. I will never again buy Oster made in China crap.

I bought what looked like a decent Black and Decker coffeemaker. Soon found it was a POS to use though the box photos didn't reveal that. I went to find price of a second carafe and second basket -- not available. Same parts problem. All the Chinese garbage is throwaway.

I note that many Japanese appliances are well supported and they make parts available. Panasonic, Toshiba etc much better than Chinese crap.

3. 75% of all product managers lie. Chinese and Indian ones more than others.
