180 owner reviews, fewer than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other home gym and fitness equipment we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
Someone easing back into exercise after time off, or working through a light rehab routine, usually needs weight that will not fight them before their form does. Polyfit's cast iron dumbbell pair is built for exactly that lane, 1.5 kilograms in a sky blue finish, sold as two pieces for $46.99. It carries a 4.8 star average across 180 reviews, tying it with the FLYBIRD adjustable set for the top rating in this comparison.
Set against the other cast iron options here, the picture is clear. JFIT sells a 3 pound neoprene pair for $7.99, and Yes4All's 16 pound cast iron and neoprene pair runs $20.12, both aimed at general strength work at a lower price point. Polyfit's $46.99 price sits above both despite its lighter listed weight, which suggests the finish, colorway, or included pair count is carrying some of that premium rather than raw iron weight.
The 180 review count and 100+ bought last month put it in a middle tier of proven demand, well short of Yes4All's 18,568 reviews and 2,000+ monthly buyers but far past a brand new listing. For anyone whose goal is light toning or recovery work rather than progressive overload, the rating record here is as strong as anything else in this comparison.
Pros
- 4.8 star average across 180 reviews ties for the top score in this comparison
- Cast iron construction offers a solid, stable feel for light movements
- 100+ bought in the past month shows steady, proven demand
- Sky blue colorway stands out from the plain black finish of most cast iron pairs
- 180 reviews is a meaningful sample, well past a brand new or untested listing
Cons
- At 1.5 kilograms per pair, it offers far less loading weight than the 16 to 50 pound options here
- Priced at $46.99, higher than both the JFIT ($7.99) and Yes4All ($20.12) alternatives despite less weight
- 100+ bought last month trails Yes4All's 2,000+ and PowerBlock's 1,000+ pace
- Not adjustable, so progressing to heavier loads means buying a separate, heavier pair

Performance notes
At 1.5 kilograms per pair of cast iron, this set sits well below the 16 to 50 pound weights covered elsewhere in this comparison, which places it firmly in the light toning, mobility, or rehab category rather than heavy strength training. Cast iron itself is a dense, stable material that will not flex or wobble in hand the way a hollow or plastic shell can, so even at this lighter weight the feel should be closer to a real weight than a toy. The sky blue color and two piece pairing point to a product designed to be picked up often and used for higher rep, lower load work like shoulder raises or light circuits, rather than the kind of heavy compound lifting that calls for the 50 pound PowerBlock pair also in this comparison.
What buyers say
A 4.8 star average across 180 reviews places Polyfit at the top of the rating scale in this comparison, tied with the FLYBIRD adjustable set and just ahead of the 4.7 posted by Yes4All and PowerBlock. The review count itself, 180, is modest next to Yes4All's 18,568 but well past what a brand new listing would show, suggesting a track record rather than a lucky early streak. 100+ bought in the past month is a real, ongoing pace, smaller than the market leaders but consistent with a reliably satisfied niche of buyers looking for a lighter, more specialized pair.

Frequently asked questions
How heavy is the Polyfit dumbbell pair?
It is listed at 1.5 kilograms, sold as two pieces of cast iron in a sky blue finish. That puts it well below the 16 to 50 pound pairs also covered in this comparison, making it better suited to light toning or recovery work than heavy strength training.
Why does Polyfit cost more than the Yes4All pair at $20.12?
Based on the listed facts, Polyfit sells for $46.99 despite its lighter 1.5 kilogram weight, while Yes4All's 16 pound pair costs less at $20.12. The price difference likely reflects the finish and colorway rather than raw material weight, though the exact reason was not detailed.
Is a 4.8 star rating from 180 reviews reliable?
It is a reasonable sample, larger than a brand new listing but smaller than the thousands of reviews behind Yes4All or PowerBlock. The 4.8 average ties for the top score in this comparison, so the pattern reads as genuinely well liked within a smaller buyer pool.
