    • Well made 10-55lbs adjustable dumbbells
Style: Pair Size: 55 lb - Copper Handle
Review Image by Tom
Review Image by Tom
*** 4 month update - Sold them about a week or two after my last update. They cleaned up nicely for my buyer. They're overkill for the way I train. If you're doing strength based training like the Starting Strength approach, you'll find yourself taking 5 seconds to change the weight, then resting the next 4minutes and 55 seconds for your next set. Would buy again if I ever need something that changes that quick. *** *** 3 Month Update - Minor scuffs from use, they go back to looking like new with a quick wipe. Nothing has broken and am comfortable with the way the weights are held by the mechanism for both Dummbell Rows and Overhead Presses. I haven't dropped them or put my body weight on them (Pushups/ManMakers). You want to slide the handle in from the side a bit for a smoother insert. Overall I'm changing my rating from 4 to 5 stars. I'm convinced these are the new standard to beat when it comes to this weight range and price.*** Safety. The handles and components that allow it to work seem robust enough. It's plastic but definitely not the cheap kind. I was concerned about reviews saying the 5-25 handles would drop plates. I have yet to experience anything like that with these 10-55 handles. Save money, check. A set of 10-55lbs fixed cast iron dumbbells will run you approximately $650 on fbm at $1/lbs. Change weights quickly between sets, check. It's not a solid solid click, but it's a solid click. Extremely satisfied with this. They're just a bit finicky when aligning the handle back on the tray. Wether there's some weight in the tray or not. I think I'll dedicate two different areas for them. One for changing weight and the other for setting down between sets. This is where I think it's lacking. Size is manageable. There will be some exercises where you will need to adapt to the length of the handles. Durability. Survived first, day so far so good. I'll update if and when they fail me. *** 3 months of use and still going strong*** ... show more

    • For the price/quality ratio—you want this set.
Style: Pair Size: 55 lb - Copper Handle
I’m sure bowflex is a superior product, but i’m not gonna shell out $500 for any adjustable dumbbell. CAP is a brand you would find around my home gym so I already knew i was getting an 80% legit product. These aren’t clanky or cheap feeling. The adjuster works pretty smoothly. They have to rebalance a certain way in your hand (which is an odd sensation) but you get used to it. Solid buy for an intermediate lifter who doesn’t want to pack up his entire gym for every road trip. ... show more

    • A perspective from a novice - a great set to start your journey!
Style: Pair Size: 55 lb - Black Handle
Review Image by TechPerspective
In Short: A really nice set of adjustable dumbbells. There are a few areas for improvement here and there, but this set can easily replace a full rack of weights for most workouts! The Longer Story: One of the downsides of getting older is that you have to take better care of your health, which means more rigorous exercise and a focus on strength. While browsing through Facebook Marketplace, I initially bought some single-weight dumbbells, but I soon realized that different exercises require different weights to train different muscle groups optimally. I am far from a pro athlete - I train about once a week - but it became painfully obvious that, for me, a 20lb weight was insufficient for a goblet squat, yet way too heavy for a lateral arm raise. Keeping a ton of cast iron lying around wasn't ideal, so I finally went the route of adjustable weights. These CAP dumbbells work well. They have an interesting mechanism where the weight can only be changed when the dumbbell is "docked" in its cradle. You simply rotate the center grip to adjust the weight in 5lb intervals (from 10lbs up to 55lbs), and the dumbbell symmetrically loads the plates on both sides. Unlike other adjustable sets, this allows you to set the weight with a single rapid movement. The only downside to this specific design is that you cannot load the sides unevenly for more obscure exercises (theoretically possible if you remove a plate from just one side, see the video). Another small downside are the not perfectly flat surfaces on the sides of the dumbbell - this makes laying them down "on the side" (vertically) a bit less stable and wobbly. The unit is very solidly built - not surprising considering the weight it has to carry. I would not necessarily toss it on the ground, but it feels reassuring enough to do overhead raises without fear of getting hit by loose weighs. As long as you are not doing any rapid-movement shenanigans with heavy weights, the loading mechanics should not be a concern. One specific feature I love is the hex shape; I use dumbbells for pushup variations, so having a set that doesn't roll away is a major plus. So, why not five stars? There are a few quirks. As you can see/hear in the video, you have to be quite delicate with the alignment of the grip inside the cradle. This can get annoying after an exhausting set where fine motor skills are fading; if you place them in a crooked fashion, the adjustment mechanism won't trigger (which is actually a great safety feature). Acoustically, you can hear the mechanism rattling a bit when you shake them, especially at lower weights. Finally, I personally would have preferred 2.5lb intervals for better fine-tuning of weights. Overall, these are minor gripes. This is a great set of adjustable dumbbells that saves a ton of space. It’s a perfect addition to my beginner workout routine, allowing me to easily experiment with different weights! ... show more

    • Well made product
Style: Pair Size: 55 lb - Chrome Handle
Thought I would give these some time before I reviewed them. They are well made. I have been using them consistently for 4 months now. They are not the kind of hex bells you can dump on the floor just because of the nature of how they are built. That said, if you have limited space like I do in my apartment and don't typically throw your dumbbells around anyway, these work great. The dial is really handy and you get an audible "click" when you make an adjustment. The numbers are clearly labeled on both sides of the unit. Grip is solid. They can be removed with no trouble and put back into the base with limited effort (Other than lining up the unit with the base which one could expect from an adjustable dumbbell). In ending money well spent. CAP has some really decent products that don't cost an arm and a leg. ... show more

I bought these for my wife as a Christmas present which she has been consistently using for over 6 months. Unfortunately, part of the plastic weight selector broke, disabling the full function. After a quick photo and proof of purchase, I have been sent a completely new dumbbell to replace the broken one. They could have ignored me or dragged out the process like other companies do, but CAP was quick and incredibly easy to work with. Honestly the slowest part of the process was me. I highly recommend these guys. On top of a great product, they have great support. ... show more
