NS Micro Viola Tuner

I need two of these: one on the right side for the strings on the left and one on the left side for the strings on the right or else the bow gets in the line of sight. (Place a thumb on the bottom of the tuner while turning it on or off with another finger and it's stable.)

I really like the D'Addario Micro Violin tuner; had bought several, years ago, for my instruments and some to give as gifts. The PWCT14 fits well on violins, and just barely on one viola, so I was pleased to see them finally offering the PWCT25 NS Viola Micro Tuner, for the viola that I play in symphonic orchestras. The good news: it fits, finds the note quickly, is easy to read, and is accurate. The disappointing: no metronome, and the power button is much stiffer that that of the old tuners - so that sometimes when pushing it the whole tuner flips off and falls. Even when pushing the clamp tight, there is a scant difference between pressure for operating the power button and causing the tuner to pop off the instrument. Re-design tip for D'Addario: If the power button will remain that stiff, move it closer to the back to reduce lever moment on the clamp.
