Query: OK--but not great.

I am a retired computer and typing teacher. I am probably much more fussy than an average user. I had one of the first curved keyboards made by Microsoft and I absolutely loved it.This keyboard makes a clicking noise every time I use the space bar. The space bar and several keys do not always push down enough when I push them. What I mean by that is that after I type a paragraph and I look at what I just typed, I now see missing letters or spaces that I know I typed in. I don't know if it is just this unit or if they are all like this.If it is just this unit, then I would rate the product higher. I will have to return this one and try another. A keyboard is a funny thing. If it doesn't have the right feel for you, you should get another.
