Any imported brands you would recommend? Not interested in any UPS that include battery by default - so no APC.
I currently have a desi UPS that I have used for ~4+ years which is obviously square wave. I am not sure how much damage it has done to the electrical equipment but I have had few desktop components and ceiling fans failing here and there.
I haven't made up my mind on buying a pure sine wave UPS because of the speculative nature of my experience. It will be expensive and also I do understand repairing of a pure sine wave UPS will be a pain - whenever it decides to conk out.
Anyone with relevant experience, please chime in.
