Microtek SEBz 850 VA Sine Wave UPS Inverter is really a fantastic Inverter. I am using this product since three month now and its working perfectly till now. I am very satisfied with its power. This excellent UPS is is really quite heavy and can even power your food processors as well. It also does not have any noise issue. The best thing about this amazing product is that its so easy to handle. After installation I does not have any problem with using this UPS. In my old Inverter there was problem of light fluctuation but not with this one. I am completely satisfied with Microtek SEBz 850 VA Sine Wave UPS Inverter.
