Durable, interesting, but not my dog's favorite.
Color: Purple, Size: Large (Pack of 1)
This is a pretty cool treat dispensing toy; the rubber it's made from is very thick and durable, and the irregular shape of it makes it more interesting for the dog.
The opening of each compartment has little strips inside that makes the toy dispense treats pretty randomly. You can also snip them so they're shorter, to dispense treats easier. I snipped all of them in my toy, because my dog was having a hard time getting treats out, and I adjusted them several times to where now it's almost too easy to get the treats out. I just couldn't find a happy medium, and of course once you've cut them, you can't uncut them.
The only real down side to this toy is that it collects dog fur and can get pretty gross pretty fast. Most of my dog's other toys stay relatively clean when she's using them, but between the material and the pattern and whatnot on the outside, this toy is just a gunk magnet. Fur collects in the little dips between "barnacles" and clings to the slots on the outside of the toy. My dog doesn't really mind, obviously, but I think it's a little gross. ;D My dog for whatever reason favors most of her other toys over this one; even when this is the only toy that still has treats left in it, she'll often ignore it. It's a very high quality toy, though.

Durable and Fun Diversion!
Color: Purple, Size: Large (Pack of 1)
At first I was a bit concerned as the toy is made of a fairly pliable rubber so I worried that my vizsla, who destroys most of his toys rather quickly, would destroy this one within hours. Luckily, I was able to quickly teach him that it's much more fun to carry and kick around, then to gnaw.
So far it's been over a month that I've actually left this on the floor, and it shows very little signs of damage. Some treats have made a perpetual home in the large and medium sides of the toy, and it keeps him interested from time to time, as he'll just randomly pick it up and start kicking it around, or bring it to me in hopes of a game of fetch or a treat reload.
One thing that definitely helped him fall in love with it was that I immediately (after washing) placed a variety of sizes of his favorite treats in the different globes. Some (kibble-sized) treats fell out easily and taught him that this was indeed a rewarding toy to play with, others took a little kicking and dropping, and some remain until they start to break apart from enough bouncing and licking, which keeps his attention.
We have the large (for a 40-lb dog) and it suits him well as he can get his mouth around even the largest of the globes to carry it, while it has about a zero percent change of becoming a choking hazard, unless a piece breaks off, which seems unlikely so far.
One does have to be somewhat careful playing fetch in the house, as it bounces somewhat unpredictably and has a bit of heft to it.
Very pleasantly surprised to find that the rubber actually smells good, somewhat like bubble gum, as opposed to some other rubber toys that reek of chemicals.
Overall, very happy with the durability, safety, and fun of this one, and wouldn't hesitate to replace it with the exact item if it is ever lost or damaged.

3.5 Stars -- Sturdy but Limited
Color: Purple, Size: Large (Pack of 1)
I got the Barnacle toy in size Large for my ~45 lb mutt. She enjoys food toys, and I wanted to find one sturdy enough that I felt safe leaving her with when I left for work since she tends to destroy her toys quickly.
First thing -- there's no way any dog is going to be able to destroy this. The "rubber" is super thick and a good balance of flexible and sturdy, so she can't do her favorite "pick at a weak edge and slowly disembowel it" trick. I've had it for a couple months now and it looks brand new.
However, it isn't great for feeding her kibble. She eats 1 cup at morning and at night, and none of the compartments fits that comfortably. I don't really feel like dividing her food into 3 portions every day to split it between either. The bigger problem is the hole size, or rather the ratio of kibble-to-hole size. The holes are very big with rubber "fingers" inside to slow the food spill. I've still found that it tends to dump a fistful of kibble all at once, or not let anything go for a long time. This may have to do with my dog's "technique", as described below.
Another problem is that since this has three separate chambers, this toy is not hollow and is surprisingly heavy. While my dog has no problems throwing a kong around (and I mean THROWING a kong around), the weight and asymmetrical shape makes it difficult to throw or roll, which is my dog's preferred way to use a food toy. This toy works best when a dog slaps it with her paws or picks it up and drops it, which may be why my dog gets frustrated with getting her food from it.
What this toy is really great for, for us, is high value treats. If I am leaving at an unusual time and anticipate that she's going to fuss, I can put "the good stuff" in this toy and then she doesn't mind the struggle at all! The different size chambers make this especially nice if I'm breaking up odd sized or home made treats and want her to stay busy for a while. Since it's so sturdy, she can chew on it all she wants, but she has to do the work to get the treats.
All in all-- this toy isn't great for my dog's daily feedings, but it's great for high value treats and a change of pace.

Actually a challenge for my genius dog!
Color: Purple, Size: Large (Pack of 1)
I am pretty sure my dog owns every puzzle toy and treat-dispensing dog toy that exists, and he's able to figure most of them out in less than 5 minutes. Many last no more than 60 seconds before he's solved them.
The Barncle, however, is actually a challenge for him!
The Barnacle has three "compartments, " none of which are connected. All three have a rubber "mouth" that helps keep treats inside. The rubber "mouth parts" are very effective and make it quite challenging to get treats out once they've been placed inside. You can trim the rubber "mouth parts" to make it easier to let treats out, but I'm not doing that. I'm glad that it's not challenge!
The Barnacle keeps my dog occupied for at least 30 minutes, which is a LONG time for my dog who usually has a "What next?" attitude towards toys.
Th only "bad" thing about the Barnacle is that it's so hard to get treats out of, even for humans. Therefore, it could attract vermin if you're not careful to clean it out.
