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

A shopper comparing budget dumbbell sets around the $40 mark will likely run into the FDS4 20LBS pair. At $39.99, it lists as a two piece set under a variant labeled 20LB(10LB Pair), meaning two 10 pound dumbbells for 20 pounds combined, a straightforward option for light to moderate home strength work.

Set against the rest of this comparison, the FDS4 pair sits below the Yes4All DSAX's 16 pounds per pair and the PowerBlock 501-00096-01's 50 pounds, but above the JFIT 20-5237's single 3 pound unit, at a price close to the Hezeyferg D-03K's $45.99 and the Fitvids SF2TRY-DB20P-3's $45.99.

Where the FDS4 set falls short is review data. A 4.2 star average across just 57 reviews is the lowest rating and smallest sample of any dumbbell in this group, and its 100+ bought last month figure matches the Hezeyferg's but trails the hundreds or thousands seen on the more established listings. That pattern suggests a newer or lower volume product that has not yet built the track record the pricier and cheaper alternatives here have, so shoppers weighing rating history heavily may want to look at the higher volume options first.

Pros

  • 20 pounds total across a 10 pound pair offers more weight than the JFIT 20-5237's single 3 pound unit
  • At $39.99, it costs far less than the $399.99 PowerBlock 501-00096-01
  • Two piece design matches the pair format used by the Yes4All DSAX and PowerBlock sets
  • 100+ bought last month shows some ongoing, active demand despite a small review base
  • In stock and available now per its listed status

Cons

  • 4.2 star average is the lowest rating of any dumbbell in this comparison
  • 57 reviews is by far the smallest sample here, next to the Yes4All DSAX's 18,568
  • 100+ bought last month is well below the 500+ to 2,000+ range seen on cheaper or pricier alternatives
  • No material spec is listed, unlike the cast iron or ABS details published for other sets in this group
  • At $39.99, it costs roughly double the Yes4All DSAX's $20.12 despite a smaller review base and lower rating

Performance notes

The FDS4 20LBS listing uses its color field to encode the weight variant, 20LB(10LB Pair), which works out to two 10 pound dumbbells for 20 pounds combined. That places it above the JFIT 20-5237's single 3 pound unit but below the Yes4All DSAX's 16 pound pair and well below the PowerBlock 501-00096-01's 50 pounds, putting it in a middle weight bracket suited to general strength work rather than the lightest toning tasks or the heaviest compound lifts. Without a published material spec, buyers cannot confirm whether the shell is cast iron, coated steel or another material the way they can with the other listings in this comparison. Combined with a comparatively low 4.2 star average and a small 57 review sample, the practical picture is a mid weight dumbbell pair with less established performance data behind it than its competitors.

What buyers say

A 4.2 star average is the lowest of any dumbbell in this comparison, and the 57 review count behind it is a small sample, far short of the hundreds or thousands seen on every other listing here. The 100+ bought last month figure matches the Hezeyferg D-03K's but sits well below the Yes4All DSAX's 2,000+ or the PowerBlock's 1,000+. Together, this pattern points to a newer or lower volume product that has not yet accumulated the review history or sales momentum of its competitors, and the modestly lower star average suggests a slightly less consistent experience among the buyers who have left feedback so far.

Frequently asked questions

How much weight is in the FDS4 20LBS dumbbell set?

The listing's variant field reads 20LB(10LB Pair), meaning two 10 pound dumbbells for 20 pounds combined, priced at $39.99. That puts it above the JFIT 20-5237's single 3 pound unit but below the Yes4All DSAX's 16 pound pair and the PowerBlock 501-00096-01's 50 pounds.

Why does this dumbbell have a lower rating than the others?

At 4.2 stars across 57 reviews, it has both the lowest average rating and the smallest review sample in this comparison, well behind the Yes4All DSAX's 4.7 stars across 18,568 reviews or the Hezeyferg D-03K's 4.8 stars across 167. A small sample size like 57 can also make the average more sensitive to a handful of reviews.

Is the FDS4 20LBS set a good value at $39.99?

It costs about double the Yes4All DSAX's $20.12 for a similar 20 pound total weight class, without matching that listing's 4.7 star rating or 18,568 review count. Buyers focused purely on price and weight per dollar may find better established value elsewhere in this comparison.
