I had purchased a su-kam inverter in June 2007. Every 2-3 weeks the inverter would stop working due to something or the other and the company takes its own sweet time to send the guys for repairs after filing a complaint, normally someone makes a visit at least a week after. So during that time the consumer has to suffer. Then the battery turned out to be faulty and they took 1 month to replace it, and did not even provide a stand-by battery. 3 months after the battery was replaced, the new one has also turned out to be faulty. It has already been 2 weeks since I filed a complaint and no action has been taken so far despite repeated phone calls to them.
Considering the power situation in gurgaon, I have suffered a lot due to this product. I will advice people against purchasing su-kam products.
