Query: Spacebar is awefully sticky

I bought this product a few days ago. I hoped that all the bad reviews are based on the old version of the product, but even today, in April of 2012 the spacebar problem is not fixed! It is impossible to use this keyboard for programming, and quick typing.Keyboard works out of box on modern Linux, except for the five programmable keys on the top of keyboard and the zoom buttons. I was able to make zoom work in Arch Linux, but I could not make 5 programmable keys to work.I did not experience the disconnect problem so it probably has been fixed.Mouse is OK, but wheel is very slow and hard to rotate. I am returning this product because of spacebar.
