Capacity & Progression Headroom
The biggest practical difference between these two sets is how far they let you progress. The FEIERDUN 70lbs tops out at 70lbs per hand — plenty for most accessory work and early compound lifts. The UNNMIIY 90lbs climbs across a 90 lbs range, so you can keep adding load without rebuying once you outgrow lighter increments. If you expect your strength to climb over the next few years, that headroom is the deciding factor.
Price-per-Pound Value Analysis
Breaking down the math, the FEIERDUN 70lbs works out to about 1.86€ per pound of capacity at 129.98€, versus roughly 2.31€ per pound for the UNNMIIY 90lbs at 207.97€. The value set wins on raw cost-per-pound today, but the high-capacity set can be the better long-term investment if it saves you buying a second, heavier set later.
