Unparalleled Quality and Realistic Feeling Adjustable Dumbbells

Many adjustable dumbbells suffer from the same set of problems and annoyances. They are cheaply made causing them to break or become non-functioniong after a short period of time. Not only is this expensive but it can be extremely dangerous. People have reported competitors products releasing plates from the dumbbell and causing significant injuries. With Ironmaster, you do not have to worry about this. Our products are guaranteed for life with a no-frills lifetime warranty. Another common complaint of competitor products is that the dumbbells do not feel like a real dumbbell. Our adjustable dumbbells look, feel, and function just like real dumbbells. They are solid and ready to go containing no plastic or fragile components. More information about this product is available below in the product details section.

5 of 5 stars Dumbbell extraordinaire!

I like dumbbells that are solid, simple, and reliable, and I know of no better adjustable dumbbell that fits the bill than Ironmaster Quick-Locks. Ideally, I'd like a room filled with hex or pro-style dumbbells. But I don't have the room nor do I want to spend that type of money. If you want an adjustable dumbbell that's a very close alternative to a fixed dumbbell, without spending a fortune or taking up an entire room with wall-to-wall bells, then Ironmaster is the clear choice.

5 of 5 stars 5 years old and going strong!

I've had these exact dumbbells for 5+ years now and they look and function exactly as they did the day that I got them. I don't know how many times I've dropped them at awkward angles on concrete and they show no signs of damage - no warp, bends, or anything. Definitely rare that you find a product that you can tell was just made to last a lifetime. I have no doubt in my mind that I'll pass these on to my grandchildren someday.

5 of 5 stars Excellent and Functional

I have been using these dumbbells for 8-9 years and the functionality of the 75lb kit has been excellent. The only issue if have had are some inconsistences with the plates occasionally creating a fit issue. The plates I have appear to have been hand ground so most are very similar but in my case 1 plate has a fairly distinguishable difference in the shape on one edge. Overall they are excellent especially for a home gym, nothing better in my opinion.
