The capo is made well. Yes, it's very light and may seem fragile, but for my use (playing at home) it's just perfect! It's easy to use (you just have to unscrew it a bit, put it on the guitar neck and screw it back till it's firmly tighten to the neck) and it's compatible with my ukuleles ( Kala tenor and Flight Travel soprano) and with my guitars (a newly bought Yamaha APXT2 (3/4 acoustic guitar) and a Ibanez TCY10E). I didn't find any issues while using it (no disturbance while playing), nor I had to re-tune the instruments. Last but not least, it's small and practical to bring with me if needed. I can only recommend this capo to all guitar and ukulele players.
P.S. "One-hand" use is NOT possible, but again, it is very easy to attach it to the guitar/ukulele neck.
