Had to modify it a bit to fit a Finnish door. One button doesn't work, but it's fine without it.

Works well even in freezing temperatures. Tuning it to a thick door requires extending the square rod and using longer screws than those included in the package. With use, the handle loosens and requires disassembling the structure and tightening the screws. However, I am satisfied with the purchase.

I don't have experience with winter yet, but so far it has performed very well compared to the fact that an electric one would have cost starting from 1500. I couldn't use battery power because the hall is also a cold space inside. If there had been a convenient transparent weather protection case available as an accessory, I would have bought it at the same time. In Finland, it can get as cold as -40C, so it must have weather protection with such a mechanical device. I recommend it, it feels high quality, so it's not just cheap stuff from China.
