  • Great product for the price.
Style: Pair Size: 55 lb - Copper Handle
I've now owned these dumbbells for about a year. I have to say, these are fantastic value for the price. My wife and I both use them several times a week, and my boys, when home, use them as well. They are solid, no mechanical issues, still good-as-new really. Pros: the variable weights allows me to use them for a variety of low-to-mid weight exercises and changing weight is simple and quick. It allows us to save space. The grip is solid, and comfortable, and feels well-made. Price is amazing for a set like this, I've priced many, and most are much more expensive than these for the same weight range. Cons: The only cons - Due to the gaps for the plate change feature, the weight is not evenly 'distributed', so if for instance, you're lifting dumbbell bench press or shoulder press - something like that, the 'bottom' will want to rotate in your hand, especially at heavier weights. You will need to rotate the weights in your hand so the 'bottom' is going to be down or they'll constantly torque your hands - it's not a major problem, just something you have to be aware of. Also, I just wish they had more weight options, like a beefier set that went up to 90 or 100. Most of those sets are very pricey, but I'm getting by with high reps, or I can just go to the gym if I really need to go heavier. ... show more

  • Great quality at a fair price!
Style: Pair Size: 55 lb - Black Handle
These adjustable dumbbells exceeded my expectations. Very solid piece of gear. Adjusting weight is simple and quick. Very good quality. Like everything else; take care of it and it will last a long time! Highly recommended!

  • Must have for smaller home gym
Style: Single Size: 55 lb - Copper Handle
After a year of using these 4 times per week, there hasn't been anything degredation. Switching weight continues to be smooth and they still feel solid while lifting. No giggling or instability. Having moved my "gym" from the workshop to the guest room (to beat the heat) these have been amazing for still having most lifts available without needing a ton of equipment. ... show more

  • (55lb pairs) really good quality
Style: Pair Size: 55 lb - Black Handle
So I just got this today, and I have only used it once.So far, I love everything about it.The way it feels and the way it distributes the weights evenly .... it's also weighted to the bottom, so you can feel how it's supposed to sit down.And where it balances.... The dumbbells themselves are really good quality.... my only complaint is the tray that the weights sit in themselves ... is plastic ..Doesnt seem very sturdy for how heavy the dumbbells definatley are. I haven't had it long enough so maybe it can withstand the weight fine... my second complaint is sometimes.When you set the dumbbell back down.If the weights move at all, it doesn't always set smoothly.. besides that, these things are just amazing.And the quality of them are so good... .It's amazing i am super happy with it ... show more

  • Easy to adjust
Style: Pair Size: 55 lb - Chrome Handle
These dumbbells work great. The weights are easy to adjust. The handles are slightly larger than standard dumbbells. I like it like that though. Helps to strengthen your grip at the same time.

  • Great space saving dumbbell set
Style: Pair Size: 55 lb - Black Handle
I live in a fairly rural area without convenient access to a gym, and I don't have a lot of space for a home gym. I had previously been using a set of dumbbells that took up quite a bit of space, even on a dumbbell rack. This design allowed me to replace all of my dumbbells with a single set. The weights are adjusted by rotating the handle until the number representing the desired weight is at the top. The numbers are easy to read, and the twisting has a nice positive stop with a click so you know you've locked into the next weight. The weights and holders are made of plastic, but they are very thick and seem durable. ... show more

  • Well made 10-55lbs adjustable dumbbells
Style: Pair Size: 55 lb - Copper Handle
*** 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

  • Great easy to adjust set for most of your dumbbell needs
Style: Pair Size: 55 lb - Copper Handle
Love the versatility of these dumbbells when I can’t make it to the gym. Easy to adjust weight, compact storage. Need to pay attention to line them up properly when putting them back, but having most of a dumbbell rack in such a compact package is worth it.
