I figured I'd be looking at a product that made a little water overnight but you'll be surprised how much actually comes through. After only barely filling the bag I could already hear flow into my collection container. Much more than the dripping I expected. They include a nice strap that is long enough for any size branch you'd want but more importantly is adjustable so you can have the filter hanging just above your container and you don't miss any water. The bag is a very nice feeling silicone-feeling material that's thick enough it wont rip easily. I'd still try to be careful around it though. The top opening is meant to be closed dry-bag style so it was intuitive. I do notice that the fitting on the filter that the hose fits over has no retention mechanism beyond a friction fit. It hasn't yet popped off for me but I feel like it's only a matter of time. The only other complaint was that the first water did end up coming out with a little taste from the bag so I recommend washing it well before the 1st use.
