Product review (5 stars): Years of camp trash pick-up shows this is still the right thing
I got my first dispenser over 15 years ago and after several refills, it's still working. These refills work just like the originals -- reliable, reasonably tough, and very easy to dispense and tie off.

Pros:
* Each of the three refills goes for many uses -- material enough for dozens of bags in each refill
* Reasonably puncture-resistant and durable enough for most trash (sticks, wrappers, camp trash, bottles, cans and so on)
* Ties off easily and tightly

Cons:
None inherent to this set of refills, though see 'other thoughts'

Other thoughts:
* Bags are narrower than I would like. Note however this is not a fault of this refill set; the size is the same as the original Coughlin's design from over a decade ago. I don't need 33-gal trash bags, but the original design is for a really narrow bag that appears to be a compromise between overall bulk and other factors. Some trash just won't fit in this bag -- you never know what people leave in a campsite -- which means either leaving stuff, or finding a different container. I end up bringing a single leaf bag on most camping trips in case there's something really large (like a tire) to remove.
