I’m setting up a home gym and need free weights. The Adjustable Dumbbells - Pair Ntaifitness NT-10014 from Ntaifitness look versatile. Rogue Fitness dumbbells are top-tier but costly. Anyone using the Ntaifitness NT-10014 for lifts? How’s it for Strength Equipment quality? I’m lifting 80lbs. Any weight tips?
