I’m a powerlifter and need free weights for my home gym. The Adjustable Dumbbells - Pair Ntaifitness NT-10014 from Ntaifitness look versatile. Rogue Fitness dumbbells are top-notch but costly. Has anyone used the Ntaifitness NT-10014 for heavy lifts? How’s it for Strength Equipment durability? I’m lifting 100lbs+. Any powerlifting tips?
