## Customer Reviews

### ⭐⭐⭐⭐⭐ Hard plastic that holds well
*by E***Y on January 22, 2024*

I like the clamps and they are hard and hold well. However they are more expensive than the alternatives that I have chosen to use. If I just need a small amount it wouldn’t be an issue but I will be using a significant number of clamps.

### ⭐⭐⭐⭐⭐ Great but make sure you size up!
*by A***R on March 10, 2019*

Very well made!! No worry's with these on the job! Just make sure you size up depending on the wall thickness of the hose your using.

### ⭐⭐⭐ too small for aquarium use
*by J***R on January 29, 2014*

these are very tight clamps, you will need to cut off the top grip to get it off. the size is very small for 1/4" tubing.
