## Customer Reviews

### ⭐⭐⭐⭐⭐ Effective
*by D***T on May 3, 2025*

I have a vintage stove with a door that had a broken spring and wouldn’t stay open. I used these magnets to keep the door closed and they work great! I’m so pleased that I didn’t have to do anything to interfere with the integrity of the stove. The magnets are strong but not so strong that the door is hard to open. They’re perfect!

### ⭐⭐⭐⭐⭐ magnets that really work
*by M***Y on March 18, 2025*

These are fantastic for handing note pads, cards, pens, all kinds of stuff on any metal surface. Bought one set, and then another. They support a lot of weight.

### ⭐⭐⭐⭐⭐ If you wear metal braces on your teeth.
*by H***S on February 2, 2025*

Magnets will “fly” from across the room. Excellent product! My single burner camping stove requires 8.8 ounce bottle of butane. (Metal bottle is size of shaving cream container.). Bottle is securely placed inside stove, but door is not latched.). Magnets keep door tight and secure. Did I say strong. Great value for money.
