My daughter thought they looked neat, so we did some searching online and looked at user reviews. Most of the reviews had mention of key touch problems had to hit them firmly, I think was the main concern.
For small kids it might be good, but if you are doing a lot of typing/keyboarding I think it would be fatiguing.

We tried to find some in local stores to do a touch test..but no luck.

I think the most reviews we found were on Amazon.
