Works good, i am using it for my replacement Fan (Delta AFB0912SH) in my Exhaust Fan Kit Electric Soldering Iron Air Blower Welding Smoke Exhaust Fan Dual Suction Blow with Power Adapter. Have replaced the stock low RPM fan Hengro HD9225H12S 0.28A for a Delta AFB0912SH High RPM 1.0A fan, becouse the one that came with it is just not enough to sock solder Smoke true a filter, but without this Excellway ZS-X4B PWN Speed controller i would run to fast and sounds like a jet plain. Also put a 12V Switching Power Supply Board in the Exhaust Fan Kit, it came with a Power Adapter, is hase more then enough room for a 12V Switching Power Supply Board in it, so do not know why they put it on the outside.

Build quality could be a bit better, but really cannot complain for this price. I plan to use it as speed controller for 775 dc motor: https://goo.gl/ckDMGJ

Quiescent current even lower than in description (that's 2.21 mA)! Can handle quite heavy loads such as 12 V 21 W lightbulb at full brightness as demonstrated in the picture.
