These dumbbell handles were a great investment for my home gym. I paired them with a set of CAP standard weight plates and with the max handles I’ve got a pair of dumbbells that can go up to over 140 lbs each. The extension sleeves were redesigned and are rock solid. They’re heavy and made of all steel. Feels like a product that’s built to last. This setup has been great for my workouts and gives the most comfortable dumbbell experience I’ve had since working out in a commercial gym. Highly recommend the max handle bundle!
