Best set of dumbells to own. Chose these over the 24kgs option and was not disappointed. The ones that offer 24kg are far too wide and awkward to use. These are perfect.

This product is great when you don't have a lot of space.
Great shade sail for the money, I bought one a year ago just to try it and it has survived Darwin weather with no issues so bought 2 more...
Nice looking dumbbells. A little bit hard line up and put back onto the rack.
Great product! Arrived in a few business days, properly packaged and easy to set up. They are simple and effective to use. Narrower than Gen1, which makes them feel more natural. I’d recommend them to anyone.
These weights are a great idea if you want to minimize how much space your gym gear takes up. Does exactly what they're advertised to do: offers you an adjustable range of weight for your dumbbells. They are a little finicky to get back into holders after using them, which you need to do if you want to change the weight - but it's a pretty minor thing and only takes a few more seconds to adjust
easy to carry in my car with kind of work I do. recommended.
