I waited almost 2 years to buy this because I was afraid of spending the money and I had seen some bad reviews. I wish I would have got it sooner. I'm not really sure if it's cheaper then regular cat litter but I was wasting money on anything that would take the nasty smell out of my house. And I would do anything to quit scooping! That being said it has been worth every penny! My cats love it and they did from day one. I was really nervous my female cat wouldn't use it cause she's a little finicky. I put it in the same place their box was before and they both took to it right away! They acted like they loved it and would sit and watch it clean! We all now cats like a clean box right. It's a no brainer! I've had it for almost a year now and just signed up for the VIC subscription. I'm pretty sure at this point anyone that is having issues it has to be user error. Oh and tech support is amazing. I had to call when I switched it to cat mode, which I also recommend using! I'm not good with directions. It was super easy and the lady walked me threw it. And she was so polite! That's hard to come by these days. The original set up so easy. That's also something I was nervous about. But I hooked it all up by myself! I could go on and on but you probably didn't even read this far lol! If so then take the plunge and make a happier, healthier, better smelling home for your cats! You'll even enjoy your fur babies more without the stinky liter paws and cleaning up after them!
