Bought this bin a week ago and already it's been brilliant... kids actually looking for things to throw away just so they can make the lid flip up all by itself - not sure how long the batteries are going to last but even for adults it's very useful. No more struggling with dirty hands to throw kitchen waste away, very neat and tidy and slimline profile takes up minimal floor-space, at 50 litres holds reasonable volume, looks smart and easy to clean...what's not to like? Body is quite lightweight mental but as long as the mechanism doesn't fail anytime soon, this looks like it's is a winner!! [This review was collected as part of a promotion.]
