Excellent build quality and so easy to use. It comes with instructions but you won’t need them. Whatever weight you set up it feels like one solid DB 👌 Very happy. 💪

Couldn’t be happier with these dumbbells. Really didn’t think upgrading from my 30 year old cast iron spin lock dumbbells would be that much of a difference but these are brilliant! The quality is top notch. The difference having a thicker handle to grip makes was not something I expected. They are so much nicer to handle. The system for changing the load is very simple and whilst it’s not as quick as some systems there is no risk of any dials or twist grips going wrong. Solid metal construction throughout should see these last for years. They are also incredible value for money.
Really couldn’t be happier with my purchase.

Easy to adjust between sets and feels much sturdier than plastic adjustable dumbbells.
