There are many other companies with slightly better prices and significantly more interest in customers. I purchased two products that, despite the description, were not compatible with my computer. I called and they walked me through a trouble shoot that was supposed to fix the problem. They assumed it was a problem with the cable. After a few weeks I called again because the problem continued. At that juncture I was told it was the battery I had purchased and they would replace it because it was too late for me to get a refund. I should mention that getting the com[any to even replace the battery was a lengthy process. The head of customer service was convinced that i was lying or something because he gave me a hard time everytime we spoke. I don't even know what there was to lie about. Anyway, they sent me a replacement and guess what, it still did not work. They are refusing to give my money back. If the products had worked in the first place there would be no issue. If they had not misdiagnosed the problem from the out set I would not have missed the time limit for refunds, where they not so condescending and dismissive, I would not be writing this note.
