    Nice set!
  

*by D***R on Reviewed in the United Kingdom on 6 April 2024*

This is my first experience with adjustable dumbbells but these are great. They fit the bill as far as saving space. I got 10 pairs of dumbbells in this one set and just turn and click for the weight I want. Very satisfied with my purchase.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good design, easy to use and good service 👍
  

*by D***B on Reviewed in the United Kingdom on 1 June 2021*

A prompt service and a good product.Not branded, but appears similar to other adjustable weights at twice the price.Weights are comfortable, feel like regular dumpbells, but please don't drop them.Don't know if the mechanics and design can withstand being constantly dropped.Rotating the dial to select the weight is easy, but you must ensure you place the weight back correctly in the aligned slot, which is easy to do.Sturdy enough, but have to see how it performs over the next 6 to 12 months.I would recommend to anyone who has limited space and an experienced weight trainer.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Decent product, very decent price, great service
  

*by A***N on Reviewed in the United Kingdom on 11 June 2021*

Very decent product for the price. I think it's the same as the original nuo flexbell (just w/o the words "nuo" on it), but about half the going rate.It's surprisingly easy to change weights and it feels very solid. The weights, handle and rod are metal. There're some plastic parts, but it all seems robust enough at the moment. I ordered two.Delivery of the second dumbell went a bit awry, but Braingain jumped on it and sorted it straight away. Then they followed up too to check all was AOK. Always a little dubious with new companies, but they did great here - hence my review.
