## Customer Reviews

### ⭐⭐⭐⭐⭐ Great value for price
*by B***B on August 12, 2025*

Work as described.wish had a little pull spot so easier when wearing gloves but still work well

### ⭐⭐⭐⭐⭐ Easy to use.
*by N***M on July 25, 2025*

Good adhesion. Work perfectly.

### ⭐ Product needs reform
*by K***S on January 22, 2025*

For me the adhesive survived a 3 hour pressure cook but does need a stronger bond. The complete failure for this product is that I believe they designer intended a 30ga needle rather than the 14-16ga needed for mushroom cultivation. That being said the user will just put gaping holes straight through this product. Sadly a complete waste of money and total failure.
