I'll try not to be unfair. The product is not of poor quality. It's just a consequence of price pressure - for the money, you can be happy that it will heat and whirr for at least six months. If you're a BFU, don't buy this product, if you're a DIYer, not afraid and it's a good price, then why not. If you want to try endless claims, that's ideal, but it's faster to fix it yourself. After all, you're not going to fix it once. It's not worth more than seven or eight hundred. The product is made of one piece of sheet metal. Once the press exploded, then it was painted, bent, the electric equipment was attached to the sheet metal with self-tapping screws and the same screws were used to close the bent sheet metal. All without the need for a single nut or washer. Not to be completely unfair, the product is luxurious and I found two featherbeds. It really couldn't get any cheaper. The consequence is zero structural rigidity. The screws are only held in the sheet metal by threads, they cannot be tightened in any way, they just turn freely at the end. Hence the complaints about the high noise level of the product in the fan version. It's just gonna vibrate the whole thing. The fan is very nice and it really makes sense to go for a model with a fan. You also get with it the only mother that the product contains. The mother is holding the plastic propeller on the motor shaft. Without any collateral. Apparently the mother was supposed to be fixed with glue, but someone must have made an improvement suggestion and saved money. I honestly don't understand how the propeller should be fixed to the motor shaft to prevent it from turning - a tightened nut locks the motor and with a loose nut the propeller rotates freely on the shaft. However, it does work, but if anyone complains about the jet engine starting sounds, here is the cause. The engine with the shaft is spinning and the free propeller is slowly starting up with the appropriate sound due to friction. Unfortunately, an unfixed mother will become loose after six months. You learn to live with it, before you buy an unnamed bolt fixer take it apart and fix it about ten times, if you don't tilt it, it will last long enough without the mother. As a bonus, the rocker switch burned out after a year, but four dollars from China buys you the same five with shipping. It's on fastons, easy to change. By the way, several home electronics manufacturers sell the product under their brand name, so go for the lowest price and only the fan version. It really helps to heat up the room faster and you'll have a lot of fun with it. Yeah, not to forget - when you find the nut (I think M4) under the heater, that's the one from the propeller; -)
