### ⭐⭐⭐⭐⭐ Solid, heavy, well made
*by I***E on June 17, 2025*

### ⭐⭐⭐⭐⭐ Good hinges.
*by B***5 on March 24, 2025*

Nice pocket hinges.

### ⭐ Spend $ On Better. Hard to install and cracked.
*by N***R on October 16, 2023*

The hinge has little ears on both sides that are very small. When you router out the pockets in the door frame (which is not a standard size) there is not enough wood to support the screws and weight of the door. The door pulled the screws out and mangled the hinge. The hinge ended up cracked an unusable.
