Query: Defective Spacebar

I love the angle in which this keyboard is designed; it's very comfortable. However, the spacebar, literally, has to be forcefully supressed in order to function. If you're a "two-finger" typist, this is not a problem - for competent typist, it's a major irritation. And to make matters even worse, once returned, it took Amazon over a month to get my money back into my account. They don't need to sell any products, and they really don't care if you return the product purchased. They make far more money investing and utilizing your money for 2-3 weeks....what a scam.Microsoft Natural Ergonomic Desktop 7000
