I've had them since July 2025.Just so you're all aware, the bar and spin lock weight is 1.6kg (without weights). Just something to bear in mind :) ### ⭐⭐⭐⭐ Good starter set *by on Reviewed in the United Kingdom 15 November 2024* Brought for my son , the weights are solid and appear well made , good for starting out and enables him to cover lots of different exercises , the only reason this is a four star and not a five star is the extension to make a barbell , just doesn't seem long enough or feel right , as dumbbells these are solid and quality at a decent price range . ## Frequently Bought Together - PROIRON 44Lbs Cast Iron Adjustable Dumbbell Set Hand Weight with Solid Dumbbell Handles Changed into Barbell Handily Great for Bodybuilding Fitness Weight Lifting Training Home Gym - ProsourceFit Puzzle Exercise Mat Β½ in, EVA Interlocking Foam Floor Tiles for Home Gym, Mat for Home Workout Equipment, Floor Padding for Kids, Black, 24 in x 24 in x Β½ in, 144 Sq Ft - 36 Tiles - CAP Barbell 2-Inch Olympic Grip Weight Plate | Multiple Options --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/47877965-proiron-cast-iron-adjustable-dumbbell-and-barbell-weight-set-connector](https://www.desertcart.co.za/products/47877965-proiron-cast-iron-adjustable-dumbbell-and-barbell-weight-set-connector) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-19*
