I've only been using this a few weeks, but it's been great so far. Being strapped for time, this accompanies me every time I do housework, the extra kg coupled with stair runs and squats has meant I can work out and sort my house out all at once.
I was worried it would only fit well for men, but the 2 adjustable straps means I get a perfect snug fit everytime. Easy to remove the weights for washing. Doesn't get in the way of shoulders for overhead exercises. Highly recommended!
