The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Overview
Anyone starting a kettlebell routine from zero usually needs more than one weight, since swings, goblet squats, and presses all call for different loads while you build strength. The Fitvids SF-KBSET5101520 is built around that problem, a graduated set that totals 50 pounds of vinyl-coated bells for $49.99.
The model number itself, SF-KBSET5101520, points to a set spanning roughly 5, 10, 15, and 20 pound increments, which lines up with the listed 50-pound total weight. That range covers technique work at the light end and general strength training at the heavier end without buying four separate products. The vinyl coating is a common choice for multi-weight sets since it's easier to color-code and gentler on floors than bare iron.
What sets this listing apart from the other kettlebells in this comparison is scale: 3,400 reviews at a 4.5-star average and 2,000+ units bought last month dwarf every alternative here, including the 2,600-review Sunny bell and the 784-review JFIT. At $49.99 for four graduated weights, it also compares well on a per-bell basis against buying single 45 or 50 pound bells separately.
Pros
- 50-pound total set spans multiple weights, roughly 5 to 20 pounds, covering technique work through general strength training in one purchase
- 3,400 reviews is the largest sample in this comparison, giving buyers far more data than any single-bell alternative
- 2,000+ units bought last month is the strongest demand signal among the kettlebells compared here
- 4.5-star average holds up well given the size of the review pool
- Vinyl coating suits color-coded, multi-weight sets and is gentler on floors than bare cast iron
- At $49.99 for four graduated weights, the per-bell cost undercuts buying single heavy bells separately
Cons
- 4.5 stars is the lowest average rating among the kettlebells in this comparison, even with the highest review count
- Vinyl-coated construction may not suit lifters who prefer the feel and durability reputation of bare cast iron
- A graduated set doesn't help someone who only needs one specific heavy weight, like the 45-pound PAETA KB00
- No handle diameter or base dimensions are listed for the individual bells in the set

Performance notes
A set totaling 50 pounds split across roughly 5, 10, 15, and 20 pound increments covers the full arc of kettlebell training. The lightest bells suit learning the swing pattern and doing high-rep conditioning, while the 20-pound end is enough for goblet squats and presses for most beginners and many intermediate lifters. Vinyl coating on a set like this typically serves two purposes: it lets manufacturers color-code each weight for quick identification, and it cushions the bell if set down hard on a garage floor. At $49.99 for four bells, the price per pound works out favorably compared to buying single heavier bells like the 45-pound PAETA KB00 at $129.99. The tradeoff is that a coated multi-weight set generally trades some of the density and feel of solid cast iron for convenience and a lower combined price.
What buyers say
With 3,400 reviews, this listing has more feedback than every other kettlebell in this comparison combined, and a 4.5-star average holding steady across that volume is a meaningful signal, it's hard to sustain a high rating at that scale without a genuinely consistent product. The 2,000+ units bought last month figure is by far the largest demand number here, more than six times the 300+ for JFIT and nearly five times the 400+ for the Sunny bell. That combination, largest review pool, largest recent purchase volume, and a rating still above 4.5, points to a set that's both popular and generally well-received, even if it isn't the single highest-rated option in the group.

Frequently asked questions
What weights are included in the Fitvids SF-KBSET5101520 set?
The model number and 50-pound total weight point to a graduated set spanning roughly 5, 10, 15, and 20 pounds, giving buyers a full range from light technique bells to a heavier strength option in one $49.99 purchase, rather than buying each weight separately.
Is the Fitvids kettlebell set well-reviewed?
Yes. It holds a 4.5-star average across 3,400 reviews, the largest review count of any kettlebell in this comparison, along with 2,000+ units bought last month, indicating consistent, high-volume demand that's rare among the smaller listings covered in this same lineup.
Is vinyl coating a downside for this kettlebell set?
Not necessarily. Vinyl coating is common on multi-weight sets because it allows color-coding between bells and is gentler on floors than bare cast iron. It does trade some of the dense feel of solid iron for that convenience, which most buyers at this price accept.
