Hi, I brought a GenTrax gen set as a back up genni as I live in the north Qld reagon and we are prone to the odd cyclone. I had it for about a month and never used it untill cyclone Marcia came here and we lost the power. I thought I would be fine as I gad a larg genset and plugged everything in and away we went. It lasted just under 100 hours before it failed badly. I contacted my ebay seller and got the run around. Parts only warranty and only after I have it repaired and only as more parts that I don't need if I have already repaired it.
I took it to a local small engine shop and old mate said he had 50 cheap Chinese inverters in there in the last month and they were really not worth fixing. He didn't even want to waste time on it.
Ebay gave me a refund after I had to start a claim against the seller. They didn't even want it returned. So I'm guessing they must have a lot coming back if they don't even bother getting them sent back.
Hope this helps bud.
