Query: DO NOT BUY THIS ITEM

I cannot overstate how disappointed I was with this keyboard. I purchased the USB version, and immediately ran into problems. No matter how many times I updated the driver and reinstalled the software, the keyboard simply refused to work.Ideazon's tech support is simply abysmal. This is a company that DOES NOT list their phone number anywhere on their website or within their literature. They do not want to talk to you. All their tech support is done via e-mail, which is inherently slow, inefficient, and ultimately pointless.To sum up, DO NOT BUY THIS PRODUCT! I am packing it up in the box it came in and shipping it back to Amazon tomorrow. What a let-down!
