The media could not be loaded. So now that I have been using the Ruborflex set for over a month, I figurerd this product definitely deserved a proper review. 1st video : the most important thing is adjustable dumbells is how seamless yet secure the switching from weight to weight is. This is the best product I have seen in seamless and safe switching from weight to weight. Every weight clicks in perfectly and the dumbell won't lift if it's not engaged properly . 1st image: the grip is precision knurled for lifting. Definitely much better than most of the smooth wear off knurled grips I have seen in the gyms. 2nd image : flat bottom gives you the advantage of stability for push-ups and likewise exercises. Yet keeping a very even weight distribution all over the hand/wrist area. 5th image: easy to lift, move around and put down without fear of shattering your fingers. Ergonomically speaking its an astute design. The matte army green looks great. I haven't seen other products in the same category offer such great color and texture finish. Overall, the ruborflex caters for everything one could expect out of an adjustable dumbell set. Great value for money. Even weight distribution and stability on both sides.

These dumbbells are great. Back in 2019-2020, I finally got the motivation to start going to the gym and putting myself into shape. But unfortunately, all the gyms were temporarily closed due to covid. So, I decided to build my own gym at home. Unfortunately, my space is very limited. And these were perfect for my situation. Saves space, adjustable weight, looks cool. As long as you treated them nicely, not dropping it, being sure each plate was aligned before adjusting it, they work wonders. Although after about a year in, one of the handles broke and stopped adjusting. So, I emailed customer service, and quickly I was able to order a replacement handle. Super easy! I received the part, replaced it, and got back to work. Just recently, the other handle stopped working as well. Same thing, emailed customer service, and ordered a replacement part. Even during holidays and weekends they were able to reply quickly. I’ve been nothing but satisfied with this product and this company. If you're debating whether or not to order this, you should do it. Other companies sell one dumbell for at least $800. For the amount it costs, this is more than perfect.

Converted my garage to a home gym. I don’t have a ton of space and nor do I have a ton of money. These dumbbells are perfect! Adjustability between weight is easy and going up by 5lbs with a twist of the wrist is awesome. Weights feel sturdy and love them. I would recommend purchasing the Roburflex weight stand because after a week I got sick and tired of bending from the ground to the weight set. Trust me on that, your back will thank you later. Only concern was a personal one. When you are used to the traditional dumbbell feel you may think these weights will slide off and hit you but with some time you do gain trust in the product and the mechanics that keep the weights locked in. Highly recommend for those not looking to break the bank nor have the space for a full dumbbell set.

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.

Love this set compared to others. Bought the rack to go with this set, all set up was great. Perfect for in home use. Just keep in mind this set really cant be used with any type of straight, EZ bar or kettlebell conversion. Wanted to use with EZ bar conversion attachment. Because of the plastic flared housing at the handles or the thickness of handles these attachments will not fit. I have bought 2 different attachments, both did not work based on handles sizing.

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.
