1 week run w/SF vs LR. Used the LR for a couple of years, no major malfunctions and it worked as advertised. The difference using SF:
The Good:
-NO litter dust - in lungs, on floor, on walls, on counters, in water dish! None, zip, nada. Worth the change for this alone.
-No weekly bagging, cleaning up box, replacing bag, carting to trash - also a huge plus.
-No pouring litter to top off. No vacuuming spilled litter; far less tracking w/SF, and one pass to clean up if needed - I use the hood and pad.
-No cleaning (yet!) any of the mechanical parts - considerable chore w/LR.
-Smaller, by about 50% in height; about the same footprint.
-Less noise, perceived about 50% less. Shorter cycle - by far, so less noise PLUS you don't hear it as long.
-Odorless, or rather, a faint "bathroom cleaner" odor. Not objectionable at all. LR was fairly odorless as well, until opened to reveal litter+kitty poo; THEN a brief whiff of nature!
-Half the price of LR, with accessories.
-No adjustment needed to detect kitty in the box; LR required tweaking and adjustment for weight of cat - sometimes aggravating.
-Easier for kitty to get into and out of I suspect.
-Maybe cartridge will not require changing for 30 days; we shall see.
The Bad:
-Expensive cartridges. But you knew that. C'mon guys, this is cardboard and kitty litter; let's get production costs down, and if they already are, let's pass it on to customers.
-Need to fiddle with cartridge some to be sure it closes properly; minor.
-It's purple. I mean, REALLY purple: grape purple, plum purple, purple Easter-egg purple. OK, some would put that in the plus column. I would point out however, that this is a LITTER BOX, not a cat TOY, and Elvis didn't decorate everybody's laundry room/bathroom.
The Ugly:
-Your kitty will need to get used to crystal litter. Our finicky Siameses did, BUT, her first response was: "Doesn't LOOK like litter, doesn't SMELL like litter, doesn't FEEL like litter. NOT my litter!" She used it, but only because it was the only game in town and she WON'T go in the house. YMMV with your kitty; be warned. This could be major for some. Now used to it and semi-loving it - at least she rubs her chin on the box.
So that's the tale (tail?) so far; would buy it again.
