I have this specific one in 20 rooms and I am satisfied.. we always have to keep in mind that we pay for what we get... It will definitely last 2 to 3 years and will break down from overheating or the switch will not turn on/off, otherwise it is okay

In the 4 hair dryers that I bought, within the first 20 days, three of them broke and the fourth one overheats and stops working. Specifically, one stopped working after a week, it went off. On the contrary, the second one doesn't stop working unless you unplug it from the socket!!! And the third one blows air from the back instead of the front!!!!
I have returned them after drilling holes and installing them on tiles.. I removed them and I am looking for others, as they were for rental rooms. A small horror... Do not approach!!!
