It came on time and as shown. Connected to a 950W heating coil and it lasted about a minute. Solder joints are very tight, and in one case, a lead from the blue voltage regulator was touching another across the gap.

I ordered the 4 pack. Definitely not capable of 2000W. Tried one on a 1500W heater and it melted. Turned the heater down to 1000W and the second one lasted about 5 minutes before it melted, so I threw the other 2 in the trash. Might be good for small fans or lights, but I wouldn’t trust them.

I cut an extension cord in half and connected the two pieces to input and output. DONE! Allows you to vary voltage to any device plugged in.. Extremely convenient! .This would be my first time playing with 110 voltage, but I figure if I keep an ion it as a experiment, I'll learn. Ask a real electrician about real hazards, likely hazards, and OK or not ( "not safe at any speeds" – Ralph Nader... but I like to tinker...

Not 2000, not 25 amp (rated just 5 amps continuous), not really PMW. However it's worth the price for dimming or speed control on a 5 amp max load.

I used this to replace a bad speed/choke coil on a 1950 Vornado fan. I am NOT an electrical guy. It was easy to install. You will need to adjust it to bring the speed control into range.

Not really PWM (Pulse Wave Modulation), Not really 25A, Not really 2000W @ 110v,but still a good unit at a good price.SCR triac used (at time of purchase) BTA16-600B (600v, 16 amp, 150 Celsius)4 amps will be about 4 watts of heat for unit .. any more than that, and extra cooling is needed.Little blue pot has a screw to adjust minimum voltage (probably fine, but adjust at your own risk)Being a triac, it turns on current mid-cycle. This can cause high in-rush current. It has an "RC snubber-circuit" and capacitor to help, but it is a sudden jump in voltage 120 times a second. Motors and resisitive loads shouldn't care, but some electronics may be sensitive (use at your own risk)This is a bare circuit board running mains AC voltage, SO enclose it in a well ventilated box.
