I purchased the 2.5 gallon one for my 2 large dogs (65 lbs+) about a month ago and it's been great! I previously just had a standard bowl and was refilling it 2 or more times a day. I fill up the waterer about once every 3-4 days and both of my dogs are pretty heavy drinkers. I didn't get the larger size just for personal preference. I would rather fill it up more frequently and know the water is being cycled through and not sitting as long. They both took right to it. I was worried the slightly gurgle sound it makes when the water is filling up in the bowl would turn them off (one of my dogs is a real chicken), but it's not loud and doesn't phase either of them. I wish I had gotten it sooner! It took me 7 months after getting my second dog to finally make the purchase, but I wish I had it even when I just had the one. I did not realize how often I was filling up a regular bowl. Haven't had any issues with it. When I go to refill I just make sure I give everything a good wipe down to clean it up and keep any mold away. Amazon's price on it can't be beat especially for the convenience factor the product provides. I highly recommend for anyone with a large dog or multiple dogs!

My first order was shipped without a top. However Amazon resolved it immediately and we love it. I clean it out periodically to avoid slim buildup but love that it doesn't need filling often. At most I unscrew the top and empty the bowl when my kittys dribble food pieces in the water. That's a huge pet peeve of mine. I like to see their water clear without debris. I also use two gallons of spring water to fill the bottle even though it contains a filter. I feel that slimy residue is slower with spring water. When we are home I tend to fill it with just one gallon of spring water so that I can wash it out more frequently. We went to the Dominican for a week, filled it with two gallons and it kept both my kitties hydrated with some water left over when we returned.

I bought this for 4 feral cats who roam our complex. I feed and water them so this was imperative, as was the continuous feeder. I rarely see the cats here and have never seen them drink water from our bowls (one drinks from the bird bath), but our gigantic neighborhood raccoon loves to partake of both food and water...as does an opossum. The waterer lasts about a week unless the raccoon decides he needs to bathe in the water. If he does that, the bowl is filthy and has to be washed. Having it has been so much better than having to water the cats everyday like I was doing. With summer coming, this will be WONDERFUL. It was easy to wash, fill and put together. The filter is somewhat futile since feral cats are drinking from it, but it's a nice feature for house cats. I use the filter, but probably won't bother replacing it. It's a nice waterer! I like it.

I had been using a metal bowl I purchased on Amazon for water for about 3 months and finally decided to try out a waterer bowl. Filling up a water bowl almost every day (sometimes multiple times a day) can be annoying. I'm not sure why it took me so long to purchase a waterer, but I'm so glad that I did. I have only been using this for a few days now but it is so great. Setup: Remove the plastic wrap around the filter! Place filter back in black cap and fill up the water jug. Screw the black cap back onto the jug and insert jug into the base. It's that easy! If you don't want to replace the filter after it is used up, you will still want to use the black cap. This helps regulate the water flow and prevent the base from filling to the brim. Quality: The entire setup is made out of heavy-duty plastic. It is very strong and durable so I don't see any issues with it breaking in the future. Overall this is a great waterer to have. The 1 gallon size is perfect for my 35 pound dog and he has no problem with using it. It saves me from having to fill his water bowl daily which is a huge plus. The base is dishwasher safe which makes it easy to clean. I still clean the water jug by hand though since it is much too big for a dishwasher (and may not be dishwasher safe). I would definitely recommend this waterer to anyone looking for one. If you have a big dog who drinks a lot of water or multiple dogs, I would recommend a bigger size. Writing in-depth reviews to help other shoppers has become a hobby of mine. I hope you found this review to be helpful! Also, feel free to ask any questions and I will answer them for you!

Our 150 pound Cane Corso mastiff was going through two bowls of water per day. I had a bad experience with these types of water feeders in the past due to them being too heavy. This is so easy to assemble and does not spell out when you put it together. This last for a good five days with our Cane Corso and small Yorkie. Still looks brand new ! Great quality !

Works great. Like others said, the filter is just a waste as it's only filtering clean water, but I'll toss it eventually... for now I left it attached. It looks pretty small compared to my 50 lb lab mix but it still keeps both my mix and my cocker spaniel with clean water for a couple of days before it needs refilling.

Great feeder, product is sturdy and great for my cats. I give them fresh water so I refill it more often that usual, but great for when I am gone for a few days. Also, of you have a stubborn kitty, who likes to tip over their water, this is great as I basically drilled it to the wall by using a .99 bungee cord and an eye hook.

Note: The lone product picture on this page (as of 4/28/2015) doesn't match the packaging on the Replendish I received. The paperboard on mine contains helpful information I would've liked to know prior to purchase, so I've added several pictures to this review to help other shoppers. Here are answers to two common questions I noticed in the product page Q&A, and wondered myself before receiving the Replendish: yes, the unit is BPA-free; and, yes, it comes with one filter. ____________________________________ First impressions: We have three cats, though I purchased the Petmate Replendish 1/2 Gallon Waterer specifically for two of them: they happen to be water connoisseurs. Their preference is drinking from faucets, and no unattended glass of water has been safe in this house for the eight years that we've had them (sisters from the same litter). After rinsing the pieces of the unit this morning and filling it from the connoisseurs' favorite faucet (judging by their preference, we ought to bottle the water from our guest bathroom's faucet and sell it at Acqua Panna prices), they immediately took to the Replendish without the scrutiny with which they typically regard new things. Our third cat, however, who daily goes into what we affectionately refer to as "stealth mode," crouching low and nervously gliding across the floor each time she notices anything is out of place in a room, regards it with her typical level of suspicion--but after about an hour, she drank from it several times. The Pieces: Altogether, the Replendish unit consists of five pieces: the base, the clear reservoir, a black cap that acts as filter housing at the mouth of the reservoir, a filter, and a plastic strap that secures the filter inside of the cap. The plastic strap is a bit of a pain to snap into place over the filter; it took me three attempts, even though I have small hands and wear my nails short. The mouth of the reservoir is threaded, so that the filter housing cap screws on to it. Then, the entire assembly of the reservoir twists about a quarter turn into the base, locking it in place. Observations: First, I'm very pleased that, with the filter in place, the water flows slowly from the reservoir into the bowl; the result is that it isn't noisy. We bought Drinkwell Platinum Fountains at two different points over the years, and the cats never got used to the loud (and sudden) gurgling and bubbling that occurred each time the equilibrium shifted enough for the reservoir to dispense water. When I first put the Replendish down, our connoisseurs began drinking without any regard for the fact the reservoir was actively dispensing and quietly gurgling. Next, one reviewer had mentioned the 1/2 gallon size didn't work for them, as the opening of the bowl was too small and too near the reservoir, so that their cat didn't like it due to its ears and whiskers being crowded. I nearly purchased the 1 gallon model as a result of that review, because our cats won’t eat out of small bowls that crowd their whiskers. However, being a starving college student, I opted for the less expensive 1/2 gallon, and the cats don't mind it. The only trouble with this size is that only one cat can drink at a time. Another reviewer indicated no instructions came with the unit, and so it took trial and error to figure out that the filter needs to be removed from its plastic wrap, and secured by a plastic strap included with the unit. As I noted above, the paperboard that came with my unit is different than the product picture, so perhaps it didn’t previously come with instructions, already assembled, and clearly labeled. However, mine arrived with instructions; the pieces were already assembled, so that by disassembling them it was impossible not to see how to reassemble them after removing the plastic from the filter and rinsing the pieces. Further, the filter housing and strap are clearly labeled as to their function. Bottom line: assembly and disassembly are simple and fool-proof. Many reviewers (and those that provide answers within the product Q&A section) seem to omit the filter. I don’t know how useful the filter is for actual filtration, since, unlike in a powered fountain, the water from the bowl--which tends to accumulate fur and crumbs of food--isn’t being continuously circulated through the filter. However, I will continue to purchase filters for the simple reason that using one causes the water to dispense slowly and quietly from the reservoir. Overall, our cats are happy with the Replendish thus far, so I’m happy with it, too. Though the opening of the reservoir (see pictures) is small enough that a bottle cleaner is required, the base doesn’t have any awkward or tight spots to clean, like Drinkwell Platinums, which are full of nooks and crannies. I’ll revisit this review in one month with an update as to whether the cats and I continue to love it. In the meantime, feel free to post comments on this review should you have questions! _________________________________ 5/29/15 Update: I still consider this a five-star product for what it is: a waterer. The cats still like it, and drink more from it than they would a bowl of water replenished as frequently. However, this is not a be-all and end-all product for me, because it requires more cleaning than a bowl (since the Replendish has more parts) or a fountain (since the Replendish doesn't circulate). I recommend this product to anyone who prefers a waterer, but will continue my search for fountains, as I do prefer something that circulates and filters the water supply.
