Dont ever make a mistake of buying this product. Their customer service is also nothing but crap. Its been three months that I have started using it and I just got frustrated like anything.
When I bought, it worked very fine and gave me upto 175 kbps of speed. After I paid my bill, these guys kept decreasing my speed. For your information, I am paying Rs. (900+ 100 taxes) for just 20 kbps of speed..
If its possible, I would like to sue this company.
