I bought something similar once. I think they were $30 for the pair. They worked well for a few months but the adjustable part of the lever started to slip out to full length constantly which I found annoying and distracting. I tried tightening the screw and various other methods but nothing was working so I just replaced them with other short levers.
The second set of short levers were also cheap but the clutch side was not formed correctly for my 04 V and caused clutch to slip, so I finally broke down and bought some shorty folding Pazzo levers and have been a happy rider since.
