Not as heavy duty of a hinge as existing blum hinge though. They fit perfectly and work exactly as described.

The black really looks nicer than the brass i had. Flip it upside down and tap with a mallet.

The first package squeaked out of the box. The second package, not so much. These are absolute junk! What a waste of money. There is a misfire.

The included screws are too small to hold them securely. When replacing existing hinges the screws need to be a larger diameter or they will not hold securely.
