Query: poor quality product

I got two copies of this keyboard and neither was good. the first copy had a very "sticky" space bar and was unusable. Both copies felt cheap and the keys required a fair amount of effort to type. It don't seem very 'ergonomic" to me to have to work twice as hard to get the same outcome. I feel this is a bad product.
