Best in Class

I've had my set for a couple of months now and I couldn't be happier with them.

Are they expensive? Yes. Are they REALLY expensive? Yes. But if you want the best of anything -- be it a boat or a bottle of wine -- it's going to cost you some money. These are the best, and they are worth every penny.

Let me also applaud Gungnir's world-class customer support. I live in Mexico (quite a ways away from Norway) and getting the dumbbells to me was a challenge. The Gungnir team was always right by my side and provided me with immediate, friendly, valuable help with every problem that arose. They are are GREAT people.

Buy these things. You will NOT be disappointed.

Premium quality and safety

These answer my desire for a pair of loadable dumbells that can be used safely for vertically oriented movements like hammer curls and tricep extentions. They work really well with my Eleiko Vulcano rubber coated steel change plates.

Get the Dumblers, as a set!

You need a set, let's get that straight now.

The handle and locking mechanisms are the foundation of any dumbbell (or barbell for that matter). The quality of the construction of The Dumbler is the best I've ever seen, and held, and if you're reading the reviews, you're probably most interested in the magnetic locking mechanism they use. It works great. Like hang it over your head and don't sweat it, great. The notches are deep and absolutely add security to the sliding lock plate. Next to that, it's a very low-profile design, making it easy to use without snagging your clothes, is good for transportation, and for storage. Knurling on the handle is equally as great.

I looked at many types of dumbbell bars and adjustable dumbbells before I settled on The Dumbler, and I couldn't be happier. If you're like me, and have been aching to add onto your home gym equipment, but want to ensure you're getting the best stuff, spend more of the budget on these foundational pieces, and buy used plates cheap secondhand. Safety first!

Exactly what I expected.

The dumbbells worked exactly as I expected.

Here are some of my initial takeaways

Pros

-Collars are extremely solid, and I feel confident and comfortable performing movements that require a vertical dumbbell (hammer curls etc).

-Cheaper alternative to something like a power block.

-They feel VERY high quality. I was actually a little surprised by how nice they feel, and how satisfying it was to move the adjustable collar. The snap and click is very satisfying. (and it better, these things are expensive).

-They work exactly like you'd think.

Cons

-Some jiggle/play between the collar and plate. Makes a noise. Might bother some people.

-Long dumbbells. Might bother some people.

-Take a long time to adjust compared to other adjustable dumbbells.

Suggestions

-If Gungnir made a plastic or rubber "end cap" to the dumbbell that made the ends flat (for when I need to rest them on my knees) I would buy a pair.
