Really tall bin. Perfect for us as I want to get as much use out of our bin bags as possible (being eco friendly and all that)! The sensor is great and also provides open and shut buttons if you prefer that option or if the sensor breaks I suppose. Only downside is that it takes 4 D batteries which are quite expensive and not just your average battery you’d have at home, but hopefully they last a while. 
All in all though nice big bin. Would recommend!
