The wrench worked fine. It seems sturdy. However, it was much smaller than I expected. It takes a lot of strength to tighten the strings and a little more leverage would have helped me control the adjustment better. That's why I give it only 4 stars. Otherwise, I'm quite happy with the purchase.
Tuning is easy - tuning really well is not. It takes time to tune over 200 strings, and as the overall tension changes, I have had to revisit some of the strings I've already tuned. My tuner doesn't pick up the low frequencies well, so I'm tuning the lowest strings by ear which is much more difficult. Also, I can't really stretch the octaves across all 88 keys so that they sound perfect. I'll probably have the piano professionally tuned at some point, but I'm very happy that I was able to make the piano quite playable again for less than $10.
Having just paid a large sum for professional tuning, I decided to buy this wrench to try to adjust them back to pitch myself. I watched the piano tuner when he was working, so I was pretty sure I knew how to make a minor adjustment. It was not hard to quickly get it back in tune.
Each key (on my piano) has three strings/courses, and usually only one is out of pitch, making the note slightly sour. I just follow the out-of-tune string to its corresponding post and adjust (righty tighty, lefty loosey). I have used this wrench to ret-tune several keys so far, so for $6, it has more than paid for itself.
I would never recommend this wrench for a whole piano tuning (88keys). It is too small and with the square (vs. star head), it is not as versatile.
It is perfect, however, for a novice to keep a professionally tuned piano in tune.
