## Customer Reviews

### ⭐⭐⭐⭐⭐ Replacement soft close slides.
*by A***N on May 24, 2025*

We were able to fix a broken cabinet drawer with these. Soft close mechanism works as it should. Great quality and easy installation. Will recommend them to others.

### ⭐⭐⭐⭐⭐ Perfect fit
*by S***Y on March 31, 2024*

Two slides provided but no screws. Was able to use previous screws from garbage door slides. Installation took less than 5 mins and worked perfectly. Anchors not provided as well.

### ⭐⭐⭐⭐ Good price. Came with all the hardware
*by G***. on April 17, 2025*

GOOD Price and it came with all the hardware and locking devices. These where almost identical to the ones I had already but for some reason they wouldn't latch in place. It seems like the opening was slightly towards the back and it wouldn't catch with the existing locking device I had there before. So I just swapped locking devices and it worked like a charm
