I think for what they offer they aren't worth the price.
Another thing I don't like is that they are marketed as being essential for that comfortable quick response and whatnot but I've tried membrane and mechanical and I think that it's not worth the extra 60-100$ for what they offer. I don't see how it is dumb to consider it to be overpriced or overrated.
Out of experience they are a bit of a gimmick for me.
If I offended you or something I'm sorry because you seem to like them quite a lot
