adjustable dumbells- 41,5 kg, black version

The product arrives in four boxes: two boxes contain the dumbbells, each with half of the plates and its corresponding base, and two separate boxes contain the remaining plates for both dumbbells. Shipping was very fast – the pair of dumbbells arrived within 48 hours of ordering, with the remaining plates arriving one and two days later, respectively. The packaging protected the product very well.

The dumbbells appear to be of high quality. The handle diameter is larger than on many other dumbbells, which requires a bit more grip strength – something I personally like (I have medium-sized hands), but it might be a challenge if you have very small hands. The knurling is fine but still provides a secure grip.

The adjustment mechanism works very smoothly. After several workouts with different weights and exercises, I can say the product feels very safe – my initial concerns about the end plate loosening or falling off proved unfounded. Returning the dumbbells to their base is easy, and weight adjustments can only be made while they are in the base.

There is no disturbing noise during use; a slight rattle occurs only if you deliberately shake the dumbbells. I especially appreciate the small weight increments (1.5 kg steps), which I find superior to many equivalent products.

Overall, this is a very good product that exceeded my expectations – definitely worth buying.
