It's actually not a bad concept, but the execution...
- Hideous red PCB
- Ugly cheap-looking case that looks jankier than the one on a 15 dollar Wal-Mart rubberdome
- People seem to hate PCB mount.
On the pro side, PCB mount means if you want to mod switches on it you don't need to do any desoldering, and standard layout means you can replace the keys as long as you stick with something that matches the ugly PCB.
...OK, if I actually needed to save space, I'd probably get one because I use the numberpad all the time(Alt codes and number entry), but I don't need to save space and by the time you slap on shipping and CA sales tax this is almost a hundred bucks for ugly.
