Bullz Competition Kettlebell

What is the difference between the BULLZ COMPETITION KETTLEBELLS and other competition style bells:

• WINDOW, THE BIGGEST DIFFERENCE, smaller size and curvature compared to other models is designed for easier insertion with comfort overhead and in the rack position during lifts. More comfort and easier insertion equal better workouts and new personal records in strength, endurace and competitions.
• HANDLE, 35mm diameter is the international standard and provides a larger surface area to push out reps
• TOP QUALITY, steel used for durable and long lasting construction
• GRAVITY CAST to specific weight, gravity casts create better surface finish and better dimensional accuracy compared to other types of molds
