We have replaced our kitchen and the double side by side bin just didn’t have a home any longer. My ideal would have been a bin hidden in a cupboard but we didn’t have a suitable cupboard so looked for a bin with the same capacity as the old one but with a smaller footprint.
When it arrived my husband said it was too small- I had to find both bins online to show him the capacity is the same. 
We have had the Totem for almost a month and it is great, no bending down for the top bin and the good caddy is an excellent idea and means food waste can be take. To the outside bin separately and more frequently.
I love the stainless steel finish and have also bought the dish rack, sink caddy and soap dispenser to match.
