This was a second purchase of a JJ Totem bin. The price is crazy but I could not now live without the life enhancing design of this bin. No-one else puts 2 recycling bins and a food waste caddy in one neat stack. 
The design has changed a bit with the tower both bins previously lived in now replaced by a sort of stand. The lower bin is therefore not as enclosed as on the earlier model, but does slide out more freely. The lid is slightly convex plastic instead of flat stainless steel- maybe easier to keep clean, but the curve is inexplicable and not as good looking. The catch feels less robust than previously- so will jave to handle that carefully. 
The dividers that used to be provided are no longer supplied, but clip points under the rim of the bottom bin allow two separate bags to be used in that one.
Overall - still pricey but still worth it!
