The 600 VA microtek UPS that I bought for my brand new computer, never worked. so I called up their official for an explanation and this is what I got in reply
1) 600 VA means that the output is only 150 VA (Awesome reply: Either he failed badly in physics or he thinks am stupid)
2) our UPS wont work in your area( chanakyapuri, new Delhi): Oh wow !!! maybe the electricity that reaches us is produced by supernatural means!!!!)
So finally, when I told him that I am myself an electronic engineer, he rudely said that he will replace the UPS, but thereon it will be my headache. so touching!!
I advice all ups buyers, never buy Microtek products, they are simply inferior quality !!!!
