Overview
Sunny Health & Fitness's No. 066 vinyl-coated kettlebell line runs from 5 to 25 lbs, and the model number on this listing, 066-5, points to the 5 lb starter weight. It's cast iron under the vinyl shell, with a flat base built for stable storage.
The vinyl coating over the cast-iron body is meant to protect flooring and quiet the bell down if set down hard, and the base is flat enough to rest upright rather than roll. It's positioned as an entry weight for warmups, mobility work, and learning form before moving up through the heavier sizes in the same line. Sunny also includes access to its free SunnyFit app for guided workouts.
- No. 066 vinyl-coated cast iron
- 5 lb starter weight in this listing
- Sizes available 5 lbs to 25 lbs
- One-hand-width handle on this size
Who it's for
Suits beginners learning kettlebell form, or anyone who wants a light single-hand kettlebell for arm-focused moves that don't call for a heavier bell. Experienced lifters wanting a two-handed swing weight should look at the heavier sizes in this same line instead.
What buyers say
From Amazon customer reviews.
Reviewers consistently call the build quality high for the price, with a smooth handle, no rust, and no sharp edges out of the box. The most common complaint is shipping speed, described as roughly a month versus a few days from other brands, and buyers who own the 15 lb version alongside this one note the smaller kettlebell's handle only comfortably fits one hand.
Strengths and trade-offs
Drawn from this product's published specifications.
- Comfortable, well-finished handle
- Vinyl coating protects floors from the iron
- Flat base allows stable upright storage
- Free SunnyFit app access for guided workouts
- Handle sized for one hand, not two
- Shipping reported as notably slow
Performance notes
The cast-iron core gives the bell its weight while the vinyl coating adds a layer that resists chipping and rust transfer onto floors. Reviewers who own multiple sizes in this line note the handle on the lighter weights, including this 5 lb version, is sized for one hand rather than two, which matters for swings and other two-handed kettlebell moves. Several reviewers also flagged notably slow shipping compared with other kettlebell brands.
