The reservoir fits on and the fountain works great. The only problem is that my cat has decided that he likes to attack it. It is pretty easy for the bottle to be knocked off and spill everywhere. The top is also very hard to unscrew and therefore hard to refill. The bowl isn't really big enough for my dog (golden retriever) and cat to drink from it all day without being refilled (why I bought the reservoir).

Works great, but one thing to know if you find the reservoir continually overflowing the bowl: the o-ring lining the grove in the lid is essential! I learned this the hard way - my reservoir did not come with the o-ring, and for the life of me I could not figure out why it kept overflowing the bowl. Finally my scientist boyfriend figured out that without some sort of o-ring to seal it, little bits of air escape out the threads of the lid, causing the water to flow out without stopping. I then read the instructions, and sure enough, there is supposed to be an o-ring in the lid! We ended up finding something at Lowes that worked in a pinch - "TEF Valve Packing 5/32" x 18" rope" - but I'll probably end up calling the manufacturer and request the actual part be sent to me. Works like a dream now - but I rate it one star short of five because it was missing the essential piece!

This reservoir is nice for the watering system I purchased for my two cats. When I go away for a couple days, I do not have to worry about stale water or water running out before I return. My one cat likes to drink from the faucet which I don't like and this watering system has a faucet like water fall and it suffices for the sink faucet. This reservoir is only part of the system I purchased, it has another part which contains the pump and main watering system.

I'd had the Drinkwell fountain for a couple weeks, as I wanted to test and see if I really needed this additional reservoir (I had a feeling I would, with 3 cats and a smallish dog). And, yeah, I do!
While the fountain holds more water than my old Petmate fountain, having the ability to add this reservoir is one of the additional things that sold me on Drinkwell.
I generally don't fill mine up to the very top, as it simply "rests" on the back of the unit - it seems really secure, but with my rambunctious brood, I don't want to chance that they'll somehow knock over and I'll come home to all 50 ounces on my floor. Even so, only filling it up half way gets me three days of use before having to fill it again (I do have another water dish in another part of the house that sees quite a bit of use). Before I added the reservoir, I was adding water nearly every day.
Cleaning it is so easy, since it's plenty big enough for me to jam my hand and dishrag down in there.
I did have small troubles with getting the lid/seal to fit back on after it's first cleaning --- I was rushing, and just jammed it all together, and tossed it on the fountain.... came back 10 minutes later to discover that I hadn't gotten the seal properly in the lid before putting it together, and this caused it to leak continuously. Lake Westgate had formed. Oy. It was my malfunction, but it's something to be aware of - that little gasket ring must be properly in place, or you'll be sad. And likely have wet socks. And have little wet animal prints on darn near everything.
Still - it's a 5 star item... the pair of fountain and reservoir have made my critter watering tasks much more simple AND I know they are drinking the water they need (instead of licking the tub, for instance).

the fountain runs out of water everyday and creates a very loud, obnoxious noise. when i bought the reservoir it continually ran through the water so that it flooded the fountain and my floor. i called the manufacturer and they sent me a replacement lid, saying it sometimes floods if the lid is curved. the replacement they sent me looks just like the old one and i'm afraid to use it. waste of money!
