This is a very powerful tool for re-stringing ukuleles, with an motorised peg winder with plenty of ‘juice’ so you could rapidly tune up and tune down. It’s not an automatic one (in that it doesn’t stop when it gets to the right note), but it has a lot more in the tank, and goes faster than the ones that do (e.g. Enya ST-1 and Jowoom T2).

It also has sting cutter for trimming off the ends of the strings when you’re done, and a bridge pin puller - to remove those troublesome bridge pins (if you have them). One of these was purchased for my workshop, for getting the strings off rapidly, and it’s so quick I got some in as it’s a handy thing to have!

It is changed via a USB cable, which is supplied, and seems to be sturdily made.

It’s not got all of the functionality of those automatic tuners, but does the job a lot faster, with others uses too, and it’s a bit less money as well.
