My kitties loved their Petmate Platinum, but I decided to upgrade it to this one so they could drink simultaneously - there was always a queue for my 3 cats to drink after eating.
It's a nice fountain, but the motor isn't nearly powerful enough. Even with just the two-flow ring, the pressure is barely enough to produce more than a trickle (and this is from new and not due to any build-up). The pump needs an upgrade in this model!
Secondly, the bowl itself gets dirty very quickly and I have to fully clean it out twice a week. The Platinum model was once a week.
I'd suggest upgrading the pump for this model as a minimum. Once it dies, I won't be replacing it with this model unfortunately. 
If it weren't for the pump, this product would get a 5 star rating from me and my (famous) blind cat would be pushing it on all of her social media platforms.
