Early tests of a prototype allowed a nurse weighing 64 kg (141 lb) to lift a patient weighing 70 kg (154 lb). A commercial version of the suit will cost about 1,200 pounds ($1,700) and could be available in two years.
That doesn't really impress me. I know that lifting a person is harder than lifting weights, but many women can easily handle that kind of weight when deadlifting. 154 lbs. isn't much at all.
If it allowed you to lift 300+ lbs. without you even trying much, then I'd say it was worth it.
