So I'm not driving this block 100% or even close. I use from 100 watts to about 500 watts. From what I've said so far, I like it a lot. I run all kinds of sensitive electronics with it and have had no issues with hum or heat from the electronics I use. The inverter itself runs very cool, and when it gets warm the fans turn on as they should. I really like the included remote control. As another viewer said, you have to be very close to use it, but that doesn't bother me. The display on the device itself is great, although it might be in a bad spot depending on your setup. Centered on the outside of the case would be better. But I knew where it was when I bought it and can't call them like some people do. If you want the display in a different location, buy a different one. But the display on the remote tells you the same thing, and you can install them side-by-side. Overall I really like this device. A 50% off coupon accidentally popped up when I bought it, so I figured out what the heck.
