I am in LOVE with this invention! I bought a CatGenie a few years ago and have NEVER had a problem or had to call customer service for help (though I've read their CS is outstanding)! I saw the newest version (the 120) was released and was thrilled and so jealous that it had the Cat Activation (automatic cleaning after sensing use) feature and the 10 hour SLEEP cycle! GENIUS!!! These two features along with the larger capacity cartridge are what convinced me to upgrade to the new version! I'm SO happy that I did! I was completely thrilled with my old version, but I really wanted my machine to sleep at night and run more (or less) often! I was a little bit leary about the machine running more often, thinking my other cat (I have two) would need to go when the machine was running, but much to my surprise, it's never been an issue! No mistakes whatsoever!
Oh! I forgot to mention, this version is MUCH quieter than the last version! It also seems to cycle faster (faster drying perhaps??)? My splurge to upgrade was worth every penny! Thank you CatGenie!!! :)
