The ROBURFLEX adjustable dumbbell is a game-changer for my fitness routine! It’s perfect for strength training at home and eliminates the need for multiple dumbbells, saving both space and money. Adjusting the weight is quick and seamless, allowing me to switch between exercises without breaking my flow. The build quality is outstanding—it feels solid and well-balanced in hand, with no rattling parts. The grip is comfortable and non-slip, even during sweaty workouts, which is a big plus. I’ve used it for everything from bicep curls to shoulder presses, and it performs flawlessly. Whether you’re just starting out or are an experienced lifter, this dumbbell is an amazing addition to any home gym. I highly recommend it for its convenience, durability, and overall design!

Peloton of Dumbbells. Can’t emphasize enough on the quality and the looks. Very proud of my research and finding this gem I did a lot of research on adjustable dumbbells and I opted against dumbbells designed like Bowflex/Ativafit as I had concerns their wide length will end up limiting motion in most exercises. So I was left with choice between these, Snode, and Core Fitness. I went with this as the colors in these dumbbells looked good and I am getting more pounds per price than the the other 2. I have used these dumbbells quite a few times and I am quite pleased with the high end quality, built, functionality and the looks. I will list down the Pros and Cons. Pros: really quick weight adjustments, amazing price per pound, weight evenly distributed, and allows wider range of motion then the bowflex/ativafit type dumbbells. Cons: Weight is in kg instead of pounds and the increment is at 4kg (i.e. 8.8 pounds) which might be considerable for a beginner. However, considering the built quality, these are totally worth the investment

I’m a bit late on the review here, but I can at least attest to the longevity of the dumbbells! I bought these almost a year ago and have used them around 2-3 times per week. They’ve held up great and I’m really happy with the way the look. Definitely nice to have something compact for a home gym! Also, one of the dumbbells looks like it had a rough time during shipping (box wasn’t in the best shape) and subsequently, the handle didn’t work. I reached out to the email address provided on the card in the box with pictures of the handle. I was pleasantly surprised to receive a punctual reply asking for a few more details and within a few days, I was given a tracking number for a package with a brand new handle. It came, I swapped it out, and it’s working great. I really appreciate customer service like that and I think it speaks volumes about a company who fixes something that was completely out of their control!

I"d buy again because they are likely one of the best adjustable dumbbells. I have one issue with one dumbbell where when I adjust it and pick it up, one of the plates always sticks and I need to double check that its not suppose to be on there, then take it off, place it back correctly on the rack. Its just slightly annoying and makes me wonder if it will eventually break. The build quality is ok, it feels like non metal parts are in there holding things together, which is concerning for a 80lbs dumbbell, but so far its held up for 5 months with lots of use.

Color: GREEN - 40LB Extendable
I just recieved this item today and it's already a 40lb piece of garbage out of the box. I placed the dumbell and cradle on the floor immediately out of the box. My first attempt to pull the dumbbell out of the cradle was successful - it was set to 25 pounds and I pulled out 25 pounds. However. When I tried to return the dumbbell to the cradle, it absolutely would not line up with one side of the remaining weights. I reset all the weights in the cradle by aligning them with the trapezoid shaped guides and then tried again. Once my dumbbell was able to align with thr remaining weight, I tried to size up to 30. However, this time, the weights refuse to leave the cradle and pulling the handle results in ALL the weights and the cradle to go with the dumbell. I have continually attempted to reset the alignment of the weights and the dumbell and continuously the handle gets stuck (can't turn), or weights get stuck, or I can't align the dumbell back in. Furthermore, just to really hughlight whatever the QA process is like for these Dumbells, the indicator on the handle is reversed -> rotating in the + direction decreases the weight and rotating in the - direction increases the weight. There is a lot of promise in these Dumbells, I like the sleek design and the turning mechanism, but if they can't even adjust weights then they're just a waste of money.

The weights are well constructed, the adjustment works well, and it feels good in the hand. I like that this set goes from 5 to 80 lbs, but this product only comes as one, not a pair. If you need two, you must purchase a quantity of two. The price point is high. I like this set very much and would highly recommend it if you don't mind the price.
