Query: sacrifices use-ability for spill-ability

I anxiously awaited this product as my old reliable IBM was on it's last, last leg. After typing for several hours, I couldn't wait to return it. Wetkeys doesn't post their return policy, so I anxiously await it and will share my experience in an addendum. Here's the problem: The space key doesn't depress with the same pressure after each word. Sometimes it skips two or rarely more spaces,more frequently it doesn't register the space. The keys take more effort-to-depress than regular keyboards, so you end up with double letters too often, especially the aa. I've had to go back and deliberately maake a space between one in five words where the space bar did not register a depression. That's way too much. Finally, after fighting with this keyboard for several hourss, my fingers ache. I've never experienced aching fingers after typing before. I can't recommend this keyboard ass it stands. It's back to the drawing board with this one.
