I’ve had one for about 18 months, used it primarily for all day trail runs/walks, Yorkshire 3 peaks and the like last year.
Can fit a surprising amount in it, lunch, snacks and more water (if its a warm day) inside and a packaway waterproof & lightweight waterproof trousers bundled up inside the external straps. Waterproofs will fit inside if you’re not taking much food (or are going to be passing a Greggs…)
The water bottles fit really securely and are easy to remove/replace on the fly.
An added bonus is that 4 mini pork pies fit really neatly into one of the waist pouches leaving the other side for keys/phone/jelly babies 😉
Doesn’t bounce around too badly if it’s well loaded. IME it tends to bounce more if its only partly full.
Started using it on the bike recently instead of a CB Mule, works very well. The waist straps are quite narrow so don’t dig in round the waist when you bend forward on the bike.
As and when it need replacing I’d buy another one without a second thought.
