They're desktop stands specifically for the xx3x size standard Genelec models, and work as fine as you'd expect from Genelec and K&M (who manufactures the stands for Genelec).
Easy to install, the design looks nice with the speaker on, the angle adjustment screw works fine, the rear cable routing is tidy, and they're very sturdy on the table. As a bonus: compared to the "tubular" stands, these pretty much maximize your free table space in front of the speakers due to the design.
Can't really fault anything about them. The price is OK considering the level of quality as well.
