I bought this capo for my banjo mandoline, but I misread the product info (my fault). It does not fit..... 
 
Fortunately it does fit my Ukulele perfectly. 
 
So,.... if you want a good ukulele capo. This is the one for you. 
 
It is a very small capo, so be carefull it does not slip your fingers and jumps away. The spring is strong, but not too strong that it ruins your tuning. Just right I would say. 
 
Mine was a little sharp around the edges, I even cut myself in the finger. Hence the 3 stars. A little sandpaper removed this danger.....
