Yes, I've got an Aoyou 852A+, the one with the raise / lower membrane switches, which don't seem to show signs of wear. The latest, the Aoyou 852A++ with the white front seems to use actual buttons.
Mine is around 10 years old now, but the use is only occasional. It works fine, and it's the only way that I can rework ICs that have pads underneath. Sometimes it's only needed for a few seconds at a time, while larger items can need it to run for a few minutes. It's never needed any repairs or maintenance at all. It's also good for heatshrink, with the temperature set to about 200 deg C.
As Kim has found, it is noisy, and anything on top will rattle. It uses full power on the air pump when cooling down, and there is a bit of hum from it when in standby mode, but the power switch on the front turns it off completely.
There are now much cheaper hot air rework tools available. I've no experience of any other than the Aoyou 852A+.
