LIFERUN Adjustable Kettlebell Set with 7 Weight Levels, 44 lb

What's a good adjustable kettlebell that replaces a full rack?

The LIFERUN 44 lb set combines 7 separate kettlebells (5–44 lbs) into one unit with a quick-change weight dial, so beginners and more advanced lifters can share a single kettlebell instead of buying a full rack of fixed weights.

• 7-in-1 adjustable range: 5, 11.5, 18, 24.5, 31, 37.5 and 44 lbs
• Quick-change dial with safety lock: switch weights in seconds; plates lock securely during use
• Space-saving: replaces a full rack of kettlebells in one compact unit
• Durable build: die-cast aluminum handle with high-density ABS construction and an ergonomic grip

Is this kettlebell the same size as a solid cast-iron one?

No — the adjustable mechanism makes it larger than a comparable fixed-weight cast-iron kettlebell of the same weight, so check the product comparison images if size matters for your storage space.
