Product "interesting."
I wanted a rack tuner visible from afar. The BTR2000 looked beefier than Kong and much cheaper than sabine.
What a disappointment! The thing is .... Wrong! If this is true if the 440Hz capped at 429, and no, it is not a problem of user setting.

I therefore serves to illuminate the rack, in any case up to that the remaining two bulbs fart too. I may keep the housing and the guts to side projects, but I'm afraid that all components are vermin ..

Seriously, save your money!
