I love it.
I've given away a lot of stuff on it, from hedge trimmers that don't work anymore, to broken kitchen appliances, books, kitchen clutter such as microwave cookware, old duvet inners and some plastic rubbish bins (all at different times).
I have a lady picking up our old computer desk tomorrow - she wanted one and I offered ours - as we aren't using it.
I've also picked up some great stuff on it, my most recent items were two pairs of swim fins/flippers which will be coming on our WBTA cruise with us in September and dropped at GW once we get to Florida - saves paying Disney prices and leaves room in the suitcase for souvenirs.
