PROIRON 20kg Adjustable Steel Dumbbell with Walnut Handle

Price and rating as shown on Amazon when we collected them. Both change.
At £89.99 the PROIRON is the cheapest set in this ranking, and it is the only one that reaches its weight without a dial: this is a spinlock pair, two 10kg dumbbells assembled by threading on cast plates, which is why the published item weight of 20kg finally confirms what arrives in the box.
The trade is a minute of your session every time you change weight, against the seconds a dial takes. What you get for the difference is real walnut on the handles and a set that one owner weighed at exactly 10.00kg per dumbbell, with every plate matching its stated weight. One thing to know before ordering: the walnut trays in the product photographs are not included, and the listing says so in its last bullet.
How those 413 ratings break down
An average hides its own shape. This is the spread behind the 4.3 stars.

Questions people ask
Is it a dial or a spinlock?
Spinlock. You thread the plates on and tighten a collar, which is slower than a dial but simpler, and it is why the item weight of 20kg is accurate.
Is the wood real?
The handles are solid walnut. The chromed plates are covered in a wood-effect laminate, as one owner points out after inspecting them closely.
Are the trays included?
No. The last bullet of the listing says the wood trays are not part of the set, even though they appear in the photographs.
How accurate are the weights?
One buyer weighed a complete dumbbell at 10.00kg, with every plate matching its stated weight and the handle accounting for 1.50kg of it.
Why is it not higher if it is the cheapest?
Because 10kg per hand is the lowest ceiling in this guide alongside the Lifepro, and changing weight takes manual work.
