Wittner Metronome 813M with Bell

I returned the first unit as it was not calibrated and the beats were uneven on a flat surface. The second one has even beats but it runs a couple BPM fast, and has an annoying metallic buzzing sound.
For such a premium price tag I also expected a better build quality: the logo on the cover is cheap plastic, the mechanism is mostly plastic (not sure how long that will last), you cannot lock the cover if your metronome is set on 60 bpm or lower, some parts of the wood are not sanded and feel rough to the touch, messy paint application on the inside, and one bit of the mechanism fell off when I opened the package.
