I never really saw the point of these until I looked in the bottom of our wheelie bins this morning. Someone's been using ours as a place to chuck their little bags of dog shit, and what look like sanitary towels. Great. I'd rather pay a few quid for someone else to deal with this ...
Thought I'd go for a one-off from www.greencleen.co.uk, as they're the first that popped up with google - any experience?
