Tried to love this bin but after giving it a go for a few months I'm looking to replace it.
Positives first: good to look at, well built, like the soft close lid
Negatives: the compression action is pretty basic and does not have anywhere near the force needed to really push down on the rubbish. I still find my own hands do a better job so this is really an expensive gimic. But the real annoyance is the way the bags attach. Rather than slipping over the top you have to do a merry dance with two bits of plastic to hook the bags in. I get why this is necessary as it ensures the bag is not sucked down into the bin when you try compressing. The problem is that when the bin is full it's nigh on impossible to get the bag off without ripping it as the tension in the bag is now so high. Really bad design imho. 
So sadly, do not recommend this model and regret the purchase.
