I thought 'Liner Included' meant that there was a liner included but there isn't.  I expected there to be a plastic inner.   This proves to me that the only way you can be sure the product is what you want is to see it.  
Motion Sensor only worked a few times. Now (a few days later) have to manually open it or use buttons.  This may be because the product was left outside (we were away) and exposed to the elements. 
My fault - I thought buying this would save me money. Where actually its a complete waste of money as (a) I've had to buy bin liners (b) the bin liners look messy and (c) I've got a product that doesn't work already.
