Overview
The Sunny NO. 066-5 is a 5-pound cast iron kettlebell priced at $16.21 in a purple finish. Cast iron is the traditional kettlebell material: dense, durable, and well suited to both lifting and weight training as noted in the product's listed use cases.
With 2,600 reviews at 4.6 stars and 400 monthly buyers, this is one of the more thoroughly reviewed options in the budget kettlebell segment. A 4.6-star average across that many reviews is a reliable signal of consistent quality, not just a fortunate early run.
At 5 pounds, this kettlebell is best suited to warm-ups, rehabilitation, high-rep endurance sets, and beginners. Lifters who have moved beyond light weights will need to supplement with heavier options.
