I purchased two of these from another company 10/16/2016 and one died on 6/24/2018, so it lasted less than 2 years. The unit was temperamental right from the start. After a month I noticed that I'd get 220V for a few hours and then at some point it would start supplying only 110V.Switching it off and then back on would reset it 8 out of 10 times and I'd get 220V again. I had some concerns about this causing issues for the devices plugged into it.The reason I did not send it back was this clause included (Not by an Amazon seller): " Products which are improperly packaged and do not include manufacturers box will be refused. The merchandise must come back packed in the outer brown box it was shipped with the shipping label on it". I had a faulty unit but his only became apparent a month later and the crappy boxes were thrown away by then.I also bought one of these from Amazon on 12/6/2017 without automatic voltage selection. It arrived with a blown fuse, so it was DoA (Dead on Arrival). Considering the issues I had with my existing unit, and the fact that Amazon is a much safer bet when it comes to returning items, I returned it. This made it clear that Simran does not do great (or any?) quality control.I continued with the original unit until it died. I opened it up to see if it could be saved and found the following:The automatic voltage selection board seems to be the culprit. The board has some component specifications on it which were not followed.Marking on board -> ComponentCap : 1000uF 50V -> 1000uF 35VResistor : 5W 10 Ohm -> 1W 10 OhmThese burned out and caused additional damage to other components.Additional components damaged was a C1008 transistor, an N4007 diode and the relay on the automatic voltage selection boardSimran used lower spec parts causing early failure. The rest of the unit seems well built and should really give you lifelong service, had it not been for the compromises made on this one board. My other unit has not given me a moment's issues, so the item you receive might be hit or miss.My advice: This product is good value for money, BUT get this from Amazon if you need it, and not from a company with questionable return policies. You may never look back or you may have to return it if you notice strange behavior.
