I bought an iphone battery recharger from Tekserve, When I bought, the salesperson said they would replace it if it stopped working. It did stop working after one month, and when I called, the technician told me that they would exchange it if I brought it into the store. When I got there, however, the technician refused to exchange it. He said I would need to send it into the manufacturer, which I did, and the manufacturer exchanged it without a problem. I had to go through a lot of extra effort because Tekserve wouldn't live up to their own exchange policy.
Cons: technicians won't accept return according to their policy
