I was looking at a Dohm sound generator on Amazon and most of the top reviews are 1 star reviews stating that the item shipped and sold by Amazon (not fulfilled by, sold by) was showing up as a cheap counterfeit. Made in China (instead of the US), fan rattling within a few days, fake UL approved sticker, etc. Amazon refunded their money but didn't appear to care about the issue, likely due to the inventory mixing between fake sellers and Amazon that seems rampant these days. I decided to buy it from the manufacturer's own site directly and cancelled the order I had just placed for vitamins to buy elsewhere.
