For 4 years, he assembled a house and a garage for me. Used mainly for screws. Shurik did not spare, he twisted screws up to 5x150 (of course with drilling and lubricating the tip of the screw, otherwise he did not pull them out) Now the first speed of the gearbox is dying (I deserve it) The gearbox costs 1600. but I think to take on more powerful. I got my money back 5 times. It will die completely - I will hang it on the wall in the garage as a keepsake.
