I have bought two other brands that have failed. One never did work and I was still charged 20% to return it! I did some research and found the Go Power to be backed by a serious company. After over two years of continuous operation, 24/7/365, it has delivered quality power to my three computers, scanner, laser printer, DVR, satellite controllers, speakers, wave radio, well, you get the picture. Don't mess around with a cheaper product, you'll end up paying more in the long run. With what I know now, I would pay the $950 list price.
I'm a mobile DJ and bought this inverter to power my 4000 watt PA/Lighting system. It replaced a modified sine wave unit that was noisy (static) through the speakers. This unit is completely quiet and actually provides cleaner power then my mains service. It works very well and doesn't seem to break a sweat running the PA and lighting system also powering a laptop, mixer and effects rack. It is light weight and feels very sturdy. All of the connections are good and will accommodate 4ga battery cables. I also like the separate voltage and capacity displays to give me an idea of how much time remains.

This was a real plug and play unit for me since I waws bypassing a modified sine wave inverter. Very solidly built.
The only reason it didn't get 5 stars is there's nothing more than bar readouts for load and voltage and I prefer meters or digital readouts.
Three plus months in operation and I have yet to see any issues.
If needed, I would defintley buy another of these.

I would not buy this brand again, based on my bad experience. However, I bought mine back in 2003, so perhaps the bugs in this model have been worked out by now.
I would've given it 2 stars, but it did get me through Hurricane Sandy by powering my 2 refrigerators (its first emergency use), so I'm thankful enough that I'm giving it 3 stars despite its bugs. Mine does not work correctly in all modes, doesn't work the way the instructions said it should work.
I found some workarounds, but they're complicated, so I had to write my own instructions and tape them to the inverter -I'm pasting them below:
A) Without remote control installed:
Problem: Inverter does not work correctly with low power loads, like a transistor radio, whether or not it's in power saving mode.
1) With power saving mode enabled, it would work for about 30 seconds or so, then turn off, when attached to low-power loads like radios.
2) Even when the power-saving mode is disabled, it still acts as if it's in power-saving mode(!): it stays on for 30 seconds or so, then turns off (at least for about 10 seconds, then I think it went back on again by itself for another 30 seconds or so, but Corina thinks it stayed off), when attached to low-power loads like radios.
Cases where it works correctly: It seems to work okay only for high-power loads, over 100 watts, even with power-saving mode enabled. I've used it successfully for my electric drill and my weed-wacker-type Toro trimmer, and it takes a few seconds to come on but it works.
B) With remote control installed:
Problem: inverter does not work correctly in power-saving mode (even though I set the dip switches as instructed, five six and seven off). When put into power saving mode using remote (hold down button for 5 seconds until green light comes on remote), inverter acts up like it did without the remote control when power-saving mode was disabled (A2 above): it stays on for 30 seconds or so (green light solid on remote and inverter), then turns off for a few seconds (green light off for a few seconds on remote and inverter), then turns back on again (and turns on again even without any load attached!)
Cases where it works correctly:
When using remote, it works fine with power-saving mode disabled using the remote (orange light solid for inverter on, orange light flashing for inverter off). Turn the inverter on and off (keeping power-saving disabled) by one press on the remote button.
Summary and tips:
Without remote, works only for high-power loads (like drills, trimmer, etc.), regardless of whether inverter is in power saving mode or not.
With remote, works only with power-saving disabled (orange light on for inverter on, orange light flashing for inverter off).
If I need power-saving mode: disconnect remote, and use only high-power loads.
If I need to use low-power loads (like CF lights or small radios): keep remote connected, with power-saving disabled (orange light), and then switch the remote on by a short push (orange light turns solid).
I bought this for the 755p. But it does NOT fit that phone. They need to advertise it correctly. A waste of time and money.
