FEIERDUN QuickDial DB1 Adjustable Dumbbell Set Review: The Adjustable Dumbbells That Finally Kill “Plate Math”

I love working out at home, but there are a few things to tackle when you’re setting up a home gym. One of the biggest is space; weights and equipment take up a lot of room. The second is cost; it’s not cheap to accumulate a full set of dumbbells in multiple weight sets. FEIERDUN neatly solves both of these with the QuickDial DB1 Adjustable Dumbbell Set, which is designed as an all-in-one, space-saving setup that replaces an entire rack of weights.

FEIERDUN absolutely hits a home run with the QuickDial DB1 Adjustable Dumbbell Set. Each dumbbell can handle up to 52.5 pounds, so the total set is 105 pounds, and it probably made my FedEx delivery man very mad at me. The whole system is built from anti-rust alloy steel with durable plastics and a comfortable rubberized grip, so it feels solid right out of the box. They come on cradles as part of the adjustable set, which does make it really easy to keep them organized, and the footprint is surprisingly compact for something that replaces so many individual weights. FEIERDUN even ships them with a strap to hold them onto the cradle if you’re moving them from place to place, which is a nice extra touch.

Once they’re unboxed, you’re pretty much ready to go. There’s a rubber dial on each end of the dumbbells, and FEIERDUN says you can adjust the weight in about a second. Once the dumbbells are on the cradle, you adjust to your desired weight goal on both sides, and you can grab them off the cradle and get to lifting. Make sure you do both sides, though, or you’re going to be surprised when one side is heavier than the other.

The dials let you lock in at varying increments, and this is where the flexibility really shines. You get 15 total weight selections, going in 2.5-pound increments up to 25 pounds, and then in 5-pound increments from there up to 52.5. It works well whether you’re just starting out or pushing into heavier strength training. There are weight plates in the cradle, and when you turn the dial, it ratchets the plates into place on the dumbbell using a secure locking system. The whole thing takes literally seconds, and once they’re locked in there’s no play or wiggle.

The unused weights are still on the cradle

One of the coolest things about the QuickDial DB1 Adjustable Dumbbell Set is that there’s nothing to think about; you turn the dial, and your weight is set. I’ve used adjustable dumbbells in the past that use individual weight plates, and you load and unload them manually. It’s fine, but there’s a weird phenomenon that happens when you’re sweating and lifting, where normal math becomes Plate Math.

And Plate Math is normal math but your brain is tired, so suddenly trying to hold numbers like “5 pound plate on one side, 5 pound plate on the other, wait what’s the bar weight, hang on I wanted to get to 20 does that get me close, what do I need to even it out, oh crap where are my 1.75 pound plates, why is math so hard.” Plate Math is mean. And the more tired you are, the worse the Plate Math becomes. So I’m thrilled beyond belief with the dial as it takes away the evil Plate Math.

In any case, the dial not only removes the Plate Math but also makes changing weights on the fly super easy and fast. It has opened up a lot with my training, because shooting for a heavier weight is easier and less risky. So, for example, last week my trainer had me doing bench presses with a leg lift, and she suggested trying for 30 pounds in each hand. I managed to get through the first set of 15, and halfway through the second, I acknowledged we were pushing just a little too hard. It took me longer to get up and cradle the weight than it did to drop them down to 25 pounds and get back to the workout.

We’ve done that a few times, or we’ve said, “Hey, it’s so easy to change the weight, let’s aim higher and worst case we drop it down,” only for me to discover, hey, I’m actually stronger than I realized. The QuickDial DB1 Adjustable Dumbbell Set’s mechanism and setup just make it so much easier to be flexible and try new things. It even supports a wider range of movements, since the design can double for kettlebell-style exercises as well.

Note the hooks that help ratchet the weight onto the dumbbell.

What amazes me is how solid the whole setup is. As I said, there’s very little wiggle or movement from the weights, thanks to the locking system. But there are more touches that make it amazing to use. The dials are rubber and feel solid, and give a nice, satisfying clicking noise as they adjust the weight. The handles are rubberized, too, with a slightly contoured shape that gives you a secure, anti-slip grip without tearing up your hands, even when things get sweaty.

I have so many weights on hand, but since the QuickDial DB1 Adjustable Dumbbell Set arrived, they’ve been my go-to for every workout. They feel great in my hands, they’re well-made, and they’re so easy to use.

At $199.99 for a single and $389.99 for a pair, the FEIERDUN QuickDial DB1 Adjustable Dumbbell Set is actually a pretty great deal compared to buying the dumbbells individually. Buying pairs of dumbbells in weights ranging from 5 to 50 pounds will not only take up a ton of space, but they’ll also run you at least $500 if not more. So, for a portion of the cost and no space constraints, you get a pretty amazing deal, plus a system that is easier to use day to day.

The FEIERDUN QuickDial DB1 Adjustable Dumbbell Set retails for $389.99; it is available on Amazon.
