2 stars only because I may have received a defective piece. The tongue broke the same day of installation and remained in an open position, pulled out. After checking, the issue was with the back screw, whose head is responsible for the tongue movement (!). I fixed it but after a few uses (the same day again) it broke again. Even if it was defective, the construction quality does not inspire confidence. I will not choose this company again and will get another one.
