Purchased and only lasted a week. Had error light but nothing was wrong with what it was connected to. Mightyape promptly sent a replacement which was good. Replacement only lasted around a week as well and had error light pop up. Turned it off and on again and it blew up with smoke and fire and nasty smell. Clearly a rubbish item. Yes it's at the cheaper end of inverters, but I have another cheaper no name inverter and it's still going strong!
