content: Do not purchase any of the items from razer. First of all, when i purchased this mouse it looks and feels very cheaply made. Its like a KINDERGARDEN TOY. At the same time i purchased a keyboard along with the mouse. When i received the keyboard the page down button was not even attached to the keyboard, the clipping was BROKEN and then the W key for the keyboard DID NOT WORK. I asked for a refund sinec i purchased the product through Razer.They made it difficut to refund. The first email i sent out was March 10, 2010 and now it is March 22, 2010 and they still have not given me a RMA number after i requested it FIVE TIMES. This is ridiculous. I will be submitting a DISPUTE to the credit card company.
