Super noisy will click all day until you go insane. Smells like death. They use some horrible oil and it heats up with just 100 watts usage and will stink up your house.

Excellent Product.

Broke down on me in under a month! Terrible Product

This regulator is just great!!!

I bought a 3000 watt and a 1000 watt just to see if I thought they would do what I needed. Although I wont know for a few more months how well they actually do work, they seem to be just what I needed. We are moving to the Philippines where voltage is not regulated so well at times from the local suppliers. We want to take many of our 110volt things with us, and I will be taking many many portable power tools I have. I tried both of these here at home by putting 220volts into them and to make sure they would start motors with surge at start up, the 3000 watt one operated a 15 inch miter-box and everything else in lower wattage I tried with no problems.

We are tacking a freezer, a fridge, and some kitchen appliances along with quite a few electronics, because good quality stuff there is very hard to find, but everything is 110volt, so need to step it down from 220 volts, just hope these will work ok on things like refrig. and freezer which need to be 24/7/365. I will go oversize with them and hope they wont overheat like some have said theirs have done.

My only complaint was the packaging from Amazon, it was pathetic. These are kinda heavy items, and they along with a plug strip were all put into one way too big box with no cushioning material at all, so they had destroyed the plug strip and had also destroyed the boxes the transformers were packed in, but the transformers themselves were ok.

I need to order quite a few more of these in various wattages, but think I will order them one at a time so hopefully they will pack them in smaller boxes with some cushioning materials in them.
