Works but the bowl is wacky
Color: blue, Color: blue
This slow feeder is actually a very good idea and my dog likes it. I blend plain, unsweetened yogurt with a little powdered pumpkin & apple pectin and thin it down with water so the roller ball can easily rotate. It's sturdy and it doesn't slip on the floor, which is good. However, I give it only three stars because the bowl inside is a ridiculous design. Instead of the inside surface being a gently sloping, smooth surface, the "legs" underneath protrude up through the inside (see photo). It makes stirring and cleanup much more difficult than it needs to be. Presumably, it's made using injection molding so it should be easy to design it with a smooth finish.

Happy licking brain stimulation!
Color: black
We have a very active 1 year old field golden and we needed something else to stimulate her brain. This has worked out beautifully for that. At first she would want to try to pick it up or move it with her paw but a few corrections and training and she’s learned to just lick at it. It stays well planted in the floor and doesn’t tip over. I had to knock it one star for its ease of use and cleaning. The inside bowl has “fins” inside that make it difficult to stir things up and mix together or to clean. Other than that minor gripe we really love it and would buy again. The enjoyment our girl gets out of is definitely worth the money. It’s been through the dishwasher several times and show no signs of wear and tear so it’s well built. Happy licking!!!

My dogs new favorite toy
Color: black
Giving it five stars because ultimately my dog loves it, it's easy to use (for the human too in terms of filling and cleaning), it feels good quality, and it serves it's purpose as advertised.
I do however think this product could be improved. It'd be awesome if it clipped into some sort of weighted tray because my dog moves this thing around the room by licking. I may try to 3D print something - solid product though, worth the money.

Frustrating but crazy fun
Color: blue, Color: blue
Maybe it’s just me and my breed of dogs but I bought 4 and within 30 seconds of placing them all down on the floor at the same time, we were down to 3… I have 3 German shepherds and a mastiff… 1 shepherd licked once and then took the whole thing in her mouth and ran out the doggy door…( if you own a German shepherd I hope this message finds you) it’s been an hour and I still can’t find the new bowl…so now we are down to 3… I blended some wet dog food and mixed with Greek yogurt for one… texture was smooth but the ball wouldn’t move fast enough for said shepherd so after some adjusting of the consistency… I still couldn’t figure it out…so as one pup is licking one ball, I grabbed the pumpkin puree and yogurt and it was still too thick… so I watered it down with a little bit of Vienna sausage juice…which now of course the crew is waiting for Vienna sausages to be dispersed among this group of terrorists….and as I’m dispersing, I noticed the bowl of wet dog food was upside down and the pumpkin puree bowl was on its side leaking orange liquid out the top… I’m still working on consistency for the remaining bowl… (mind you, we have already had breakfast which consisted of sausages from the oven as we love beer brats for breakfast… 3 cans of wet dog food that all the babies line up for and are spoon fed -and a couple pieces of cheese as I was prepping dinner) ok so now I have a runnier consistency with adding that sausage juice…got it to where I could move the ball pretty easily but then once again it got too dry and the ball just kept getting licked and nothing was sticking to it…when taking the device apart, I noticed that the liquid has no problems being licked up but the problem is that the thicker product gets stuck on the sides and the ball can’t pick it up for some reason… it needs to be nectar consistency or thinner for my family…as I’m seeing… during this whole time I’m mixing different consistencies on my counter… holding on to one with my foot as they do not stand up against large breed mouths, slide all over and also trying to make sure they stayed safe in the home as these were not the cheapest…and holding one in my hand for my special needs shepherd…these things were slipping all over the floor. They are heavy and feel durable but someone back me up here… I have learned so much about my breed of the GSDs… but my life has changed so much since having these babies because learning what can stand up to these dogs is a daily-no-HOURLY TASK. My dogs do not find enrichment activities fun. They bore easily and that’s probably my fault… so when I saw these enrichment bowls I was pumped!! The treat mats, (were shredded within minutes of realizing we couldn’t get treats out quickly) the boxes with the *whack-a-mole” cheese stick games…the poor Amazon box that I so carefully cut holes into did NOT see my shepherds mouth coming… these special toys that the dogs have to roll around to release a treat… no. No. No. I’m still finding chunks of THAT poor toy… these should not be called ‘slow feeder dog bowls’ liquid treats yes but the videos of the dog owners making the yummy stuff to go inside need to be a little more specific… as we all know, all dogs are different… but this product was supposed to entertain the puppers for a little bit but 24 hour supervision is required in this home which is not ideal… I need to get a few things done daily without the assistance of 3 Velcro dogs… impossible with the new enrichment bowls… I’m not going to return them, my dogs love them once they understand to stay put and lick but my dogs consume things so fast that now it’s just another activity to do with them daily which is fine… but if you have certain breeds it might save your couches and shoes from being chewed but now with the way I have to monitor these things and constantly refill the bowls…( my dogs had them cleaned out in about 3 minutes each) all in all, this was not a smart purchase for me as it’s now added more work to our already busy routines… I can only do 1 star…aftermath photos

Good for a laugh at least and a messy kitchen
Color: black
While design, quality, and ease of cleaning are great!! These are not for highly food motivated dogs and puppies.
My senior dog (100lbs) took a couple licks, he immediately proceeded to pick it up as one unit and carry it to his bed where immediately tore it apart to get to the good stuff. ~ I will say that it is durable and did not fall apart as he carried it.
My 7mo old puppy (60lbs) was intrigued and quickly impatient and was able to flip it over and while this only made a little pumpkiny mess, what he did next was hysterical! He picked it up on the edge and threw up in the air and the mess surprised even him but only for a moment. He promptly did it again and on the third time he was able to break the top loose from the bottom and quickly cleaned up the toy and the mess on my kitchen floor and cupboards.
Fair warning for those with energetically food motivated labs!! These have since been donated to local shelter with the same warning.
