They feel solid and well-balanced, with a durable cast iron finish that gives confidence during every workout. The weight is accurate, and they’re comfortable to grip, even during longer sessions. I like how versatile they are for a wide range of exercises, from bicep curls to shoulder presses and full-body workouts. They’re compact, easy to store, and don’t feel flimsy like some cheaper alternatives. Overall, these dumbbells are sturdy, reliable, and great value for money. Ideal for beginners and more experienced users alike—definitely a worthwhile addition to any home gym. Review: Great Weights for price - A great set of weights, use them daily, only thing i’ve noticed is that the lengths of the bars are different which is understandable as it makes it easier to screw into other bar which then creates the barbell. Always make sure to retighten screws after using weights. Grip is good as i use gloves and great value worth the price. ## Features - 20kg / 44lb Set: 4 x 0.5kg (1.1lb) plates, 4 x 1.25kg (2.75lb) plates, 4 x 2.5kg (5.5lb) plates (all cast iron), 4 x Spinlock Collars, and 2 x 35cm (14") Chrome Spinlock Bars (Total weight includes bars and collars). - Durable Cast Iron Construction: Made with high-quality cast iron for enhanced durability, toughness, and stability, ensuring long-lasting performance during your workouts. - Comfortable Non-Slip Grip: Upgraded grip design with high-grade rubber coating to prevent calluses and discomfort, even during intense, sweaty sessions. - Spinlock Bars & Collars Included: Set includes chrome spinlock bars and collars for secure and easy plate adjustments, allowing seamless transitions between exercises. - Compact & Space-Saving Design: Dumbbell heads prevent rolling and minimize storage space, making it ideal for home gyms and fitness classes. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DG9BVW1M | | Best Sellers Rank | 33,072 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) 253 in Dumbbells | | Brand Name | DUAS | | Colour | Black | | Country of Origin | China | | Customer Reviews | 4.6 4.6 out of 5 stars (42) | | Handle Diameter | 35 mm | | Handle Material | Rubber | | Item Weight | 20 Kilograms | | Manufacturer | DUAS | | Material | Cast Iron | | Number of Pieces | 26 | | Other Special Features of the Product | Adjustable Weight, Encased, Non-Slip, Unbreakable | | Style | Adjustable | | Target Use Body Part | Arm, Shoulder | | Unit Count | 1.0 count | ## Product Details - **Brand:** DUAS - **Colour:** Black - **Item weight:** 20 Kilograms - **Material:** Cast Iron - **Special feature:** Adjustable Weight, Encased, Non-Slip, Unbreakable ## Images ![Adjustable Cast Iron Dumbbell & Barbell Weight Set with Spinlock Bars and Plates for Home Gym Strength Training, 15kg 20kg 30kg & 50kg Weights for Fitness, Muscle Building and Workouts - Image 1](https://m.media-amazon.com/images/I/710N+RI-mcL.jpg) ## Available Options This product comes in different **Item Weight** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Solid, Durable, and Great for Home Workouts *by C***R on 25 January 2026* These cast iron dumbbells are excellent quality and perfect for strength training at home.
