It is big, very BIG
Easy to assemble.
I had bought this with the idea in mind of putting in the same place as the old tray (Which is one standard kitchen cabinet wide) much to my surprise it was too big by a couple of inches.
Use is not as clearly defined as in the description, a single pull of the level all the way forward can result in all the cat litter in the waste tray, it needs a slow pull with a shake action to filter out the clumps, then upon returning the handle take it past the start position and all the way back, again a shaking is needed to bring the litter back out of the sifting device.
Taking the above into consideration it does what it says (just not as efficiently as suggested) it comes with two of each liner and a single carbon filter so you will need to buy spares at the same time.
