The Eisenlink is one of the few listings in this category that answers the pair question before you have to ask it: the bullets say plainly that this is a single dumbbell, the colour field reads Single Dumbbell 20kg, and the item weight of 20kg matches what arrives — one dumbbell, not two.

The square body is the other reason it is here. Without a base it can be set down anywhere, and the plates snap in rather than thread on, so nothing works loose mid-exercise. The catch is the arithmetic: £110.00 for a single 20kg dumbbell is poor value next to the DH FitLife, which gives you a 18kg pair in twelve levels for £164.99. The same product also appears under a second ASIN at £239.90 while sharing this listing 241 ratings.

## Questions people ask

**One dumbbell or two?**

One. The bullets state it, the colour field says Single Dumbbell 20kg, and the 20kg item weight confirms it.

**How many increments?**

Nine stages across 4 to 20kg in 2kg steps, the smallest jumps in this ranking.

**Why is it ninth if the increments are the finest?**

Because it is a single dumbbell at £110.00, while the DH FitLife pair costs £164.99 and reaches 18kg per hand with twelve levels.

**Does it need a base?**

No. The square body can be set down on the floor between sets, which is why it is easier to live with than a rounded dumbbell.

**Is the second ASIN worth checking?**

Yes. The same product is listed at £239.90 on another page with the same review pool — buy from the cheaper listing.
