I will be honest — I did not expect to care this much about a pair of dumbbells. When I ordered the 15 lb pair of Northdeer’s adjustable black steel dumbbells, my expectations were modest: something compact enough for my living room that would not embarrass me every time a guest walked in. What I got instead was a set of weights that I genuinely look forward to picking up every morning.

Weight Adjustment Options by Model
One of the most practical features of these dumbbells is the ability to train across multiple resistance levels without buying separate pairs. Here is the full breakdown of what each model can be adjusted to:
| Model (Pair) | Available Weight Settings | Approx. Item Weight | Best For |
|---|---|---|---|
| 5 lb Pair | 3 lb, 4 lb, 5 lb | ~5 lb per dumbbell | Beginners, rehab, toning |
| 10 lb Pair | 5 lb, 7 lb, 8 lb, 10 lb | ~8 lb per dumbbell | Light-to-moderate training |
| 15 lb Pair | 7 lb, 10 lb, 12 lb, 15 lb | ~12 lb per dumbbell | Intermediate strength work |
| 20 lb Pair | 10 lb, 14 lb, 16 lb, 20 lb | ~16 lb per dumbbell | Progressive overload, CrossFit |
I purchased the 15 lb pair, and the ability to drop down to 10 or 12 lb mid-session for higher-rep sets made the whole routine genuinely more versatile. The adjustment itself — simply unscrew a plate, remove or add, rescrew — takes about ten seconds per dumbbell once you get the hang of it.
Build Quality: Does the Steel Construction Hold Up?
The first thing I noticed when unpacking these was the weight. Not in terms of actual poundage, but in the way they feel — dense, solid, with zero wobble. Northdeer machines each dumbbell from a single piece of high-quality alloy steel without welding, which means the plates lock together cleanly without the annoying rattle you get from cheaper sets where the nut gradually loosens over time.
The black lacquer coating is genuinely impressive. I have had chrome-coated weights chip after a few months of regular use, but after consistent daily sessions, the finish on these remains crisp. It does not scratch easily and the color stays true — no fading, no surface rust developing at the edges. Several Amazon reviewers echoed the same sentiment.
Verified buyer Multitasker, who is on her fourth set, wrote that she keeps both black and chrome versions and finds them reliably consistent in quality across every purchase.
“Fourth set I’ve purchased! These are easy, beautiful, space-saving weights. Have both black and chrome. Simple to adjust. Get extra sets to mix and match weight.” —Multitasker
The foam handle deserves its own mention. Unlike bare steel or knurled iron handles that become cold and slippery in winter, the closed-cell foam grip stays warm to the touch and provides just enough texture to keep your grip secure even when you work up a sweat. Japanese buyer TOKYO SKYTREE さん specifically called this out, noting that their previous iron dumbbells felt uncomfortably cold in winter while these never posed that issue.
Comfort and Ergonomics During Training
When I first wrapped my hands around the 15 lb version, the grip diameter felt slightly narrower than a standard barbell. For most people — particularly those with average or smaller hands — this is actually a feature, not a flaw. The smaller circumference reduces forearm fatigue during higher-rep sets and allows you to maintain a secure grip throughout lateral raises, curls, and overhead presses.
That said, if you have large hands, this is something worth knowing upfront. One Amazon reviewer, FL Guy, found the 1.4-inch handle diameter too narrow compared to the 1.5-inch handles he was accustomed to and ultimately returned the 20 lb set for this reason. If grip width is a concern for you, I would recommend checking the handle dimensions carefully before purchasing the heavier models.
Living Room Friendly: Aesthetics and Space Saving
I keep my dumbbells in the living room, and I will not pretend that appearance does not matter. These are genuinely good-looking pieces of equipment. The matte black finish with a subtle sheen looks more like an architectural object than a gym accessory, and because the design is compact and stands upright, they take up a fraction of the floor space traditional dumbbell sets demand.
A Japanese reviewer summed it up well, describing the design as motivating in itself — noting that seeing a beautiful piece of equipment within reach makes you far more likely to pick it up and actually train. That rings completely true in my experience. These sit beside my couch and I genuinely reach for them more often because they look like they belong there rather than being awkwardly stashed in a corner.
“I keep them in my living room so that I see them next to my couch and remember to lift them every once in a while. They are pretty easy to change out the weights. I would recommend and I would buy them again.” — Jess
Peter B. Weir, who bought the 15 lb pair for his wife, made the same point: they live in the living room where they get “a lot of views,” and the design is attractive enough that they do not feel out of place in a home setting. For anyone doing a small apartment home gym setup, this visual appeal is not a trivial consideration.
Pros and Cons
What I Love
- Premium matte black lacquer finish that does not scratch or fade
- Single-piece steel construction — zero plate wobble or rattle
- Comfortable, warm foam handle that reduces palm fatigue
- Compact and upright storage — ideal for small spaces
- Quick plate-swap adjustment system takes under 15 seconds
- No plastic shell means no chemical odors during training
- Multiple weight configurations per model (4 settings on 15 lb+)
- Stylish enough for a living room, home office, or bedroom
- Consistent quality across chrome and black versions
What Could Be Better
- Handle diameter may feel narrow for men with very large hands
- Included rubber rings feel unnecessary to most users and can fall off
- Plates can feel slightly slippery mid-swap on sweaty hands
- No dedicated storage rack or stand included
- Premium pricing vs. basic fixed-weight alternatives
- Black weight plates not available separately for color matching
A Word on the Rubber Rings
The included rubber rings are meant to sit in the grooves of the dumbbell plates to protect hardwood and tile floors. Conceptually, this is thoughtful. In practice, the consensus across dozens of reviews — and my own experience — is that they are more nuisance than aid. They are slightly oversized, pop off during plate adjustments, and if you are changing weights multiple times per session, you will likely stop bothering with them after the first week.
Where they do make sense is in a specific use case: heavy static holds on delicate flooring where the weight will not be moved frequently. If you work out on hardwood and rarely adjust the weight mid-session, put the rings on and leave them. Otherwise, just set the dumbbells on a mat and forget about the rings entirely.
Who Should Buy Which Size?
| Your Profile | Recommended Model | Why |
|---|---|---|
| Complete beginner, returning from injury, or focused on rehab | 5 lb Pair | The 3–5 lb range supports controlled movement and muscle activation without joint stress. Verified buyer Mohammed Islam described these as his first-ever exercise equipment — perfect entry point. |
| Light-to-moderate trainer, upper body toning focus | 10 lb Pair | The 5–10 lb range covers most isolation movements and allows meaningful progression over several months of consistent training. |
| Regular home gym user, intermediate lifter, CrossFit supplemental work | 15 lb Pair | Hits the sweet spot of versatility. My personal choice — the four weight settings cover warm-up through working sets across most dumbbell exercises. |
| Experienced lifter, progressive overload program, CrossFit main use | 20 lb Pair | The 10–20 lb range supports compound dumbbell movements like Romanian deadlifts, rows, and goblet squats alongside typical isolation work. Lonnelle Neavear described these as her go-to for CrossFit sessions at home. |
What Longtime Users Are Saying
Beyond my own experience, I spent time reading through the full range of buyer feedback — not just the top reviews. The pattern that emerges is consistent: the build quality genuinely impresses people who have tried multiple adjustable dumbbell sets. Jeffree Rynearson, who gave the 15 lb pair five stars back in 2023, put it simply: “If you’re thinking about it, think no longer, they are worth it.” Three years of continued strong reviews suggest that sentiment has held up.
“The process of switching out weights is straightforward and simple and they do lock in place very well… Overall I’d say these are excellent and worth it.”— Peter B. Weir
One standout piece of feedback came from a Japanese reviewer who described the plate-threading experience as genuinely enjoyable — the screw mechanism operates so smoothly that adjusting the weight feels satisfying in itself. That kind of tactile quality is rare in gym equipment at this price tier and speaks to the precision of the threading cuts.
Among the critical reviews, the only recurring substantive complaint beyond the rubber rings is the handle diameter — and even the reviewer who flagged this specifically praised the design, construction quality, and adjustment method. That is a narrow set of drawbacks for a product that otherwise consistently earns praise across hundreds of purchases.
Final Verdict
After weeks of daily use, these have genuinely changed how consistent I am with my home training. The combination of beautiful design, reliable build, and practical adjustability removes the friction that usually kills home gym routines — no cluttered rack of individual weights, no ugly equipment fighting for space, no complicated selector mechanisms to fumble with between sets.
The foam handles deliver real comfort advantages during longer sessions, the steel construction feels premium in a way that reinforces confidence during heavier lifts, and the matte black finish holds up beautifully over time. For anyone building out a space-conscious home gym, particularly in a living area where equipment needs to blend into the environment, these are an outstanding choice.
The rubber rings are a minor annoyance and the handle diameter may not suit everyone with very large hands — but neither of these flaws undermines what is otherwise one of the most thoughtfully designed compact dumbbell sets available. The fact that multiple buyers are on their third and fourth sets says more than any star rating could.
