Great to add weight to your dumbbells
Andrew L.—October 26, 2025
Bought these as incremental weights on my adjustable dumbbells. Goal was to add 2.5 lbs, because my dumbbells only adjust at 5 lb increments. Got a pair of 4.9" magnets, they weigh 1.6 lbs each, and a pair of 3.2" magnets, which weigh 0.8 lbs each. So now depending on what I'm lifting, I can customize my 20 lb dumbbell to 21.6, 22.4, or 24.2 lbs by attaching these magnets. They're strong magnets so I don't have to worry about them falling off while I lift, but I can slide them off the end easy enough. Read more

Good Strong Magnets, Mostly!
Grant County Golfer—February 27, 2025
But it appears that the shielding part is made of stainless steel which does not conduct a magnetic field very well. The only reason this matters is in the way I use these. I've tied them to winter golf tees, rubber tees with various heights. If the shiny side is up there is very little magnetic pull, needs to be flipped over to pick the tees up. I'm well into my 70's and need every convenience I can find! Other than that these are well made. I think I'll heat one up and see if I can break the glue bond holding the two pieces together.

Very strong magnets 🧲
frank—December 12, 2025
These magnets solved my problem of always having to unbolt my vice from my welding table to reposition it for the job I was doing. A real time saver. The description is very accurate and they are a little over 3" round with a center hole that fits a 1/4" bolt and a nice chrome finish. Read more
