| Remark | When using the Big Operating Cylinder, the stroke amount of the cylinder decreases, so please adjust the stroke as necessary. 1) Be sure to clamp the hose with a hose clamp to prevent air from entering before removing the standard operating cylinder. 2) Fill the Big Operating Cylinder to be replaced with Brake fluid, remove air beforehand and connect it to the Hose. 3) Even if you do 1), 2) work, air enters the piping. Once the air enters the piping, the pedal stroke and feel change. Because it is difficult to remove air from the thick diameter U-shaped pipe etc, please bleed sufficiently. 4) To facilitate the work of 3), air bleeding by vacuuming is effective (Please use the U-shaped pipe dismantling adapter attached to the NISMO clutch hose). |

My pup really loves this toy!
I think they are adorable. and my pup loves them! We have a golden puppy and she loves to chew and play with her toys. This is one of her favorite toys. She enjoys tugging at the legs and making the squeaker squeck! I love my puppy and she loves this and I highly recommend these!

Not good for aggressive chewers
This product does not stand up to aggressive chewing. My bulldog had it for about an hour before the legs disappeared.

Cute donuts. Not destroyed (yet!)
These squeaky doughnuts are really cute. It’s a bonus that it comes with two. I didn’t realize that when I ordered. I have two dogs and now they won’t fight over a doughnut just kidding one dog is 14 and doesn’t play with toys anymore. The other one is six and loves toys but for some reason he’s not really into this one maybe this will change but for now he only goes after it if I throw it, I’ll update this review to comment on durability if and when he starts playing with the toy, but for now it’s very adorable because it’s just sitting on the floor.
Update: he picked one up only because I put it in front of him to take the photo!

Double the Fun
This two-pack was a really nice surprise. The toys are super cute, soft, and just the right size for carrying around, which made them an instant hit with my pup. He loves having a toy he can easily grab and parade around the house, and these are perfect for that.
The plush material is soft enough to make them great comfort toys, but they also have that fun squeaky element that keeps things interesting. I like that getting two in the pack gives a little backup when one gets slobbery or needs a quick cleanup.
These are better for gentle play and cuddling than for heavy chewing, but for a puppy or dog that likes soft carry-around toys, they are a great choice. Adorable, fun, and a good value for a two-pack.

Durable
This is the best dog toy I have ever bought! I got my 1st one in 2013 and it still squeaks. Admittedly, there is only one squeaker left but it still works. My dog has played with this silly snake more than any other toy she has. My friend often brings her dog when she visits and then the 2 dogs play tug-of-war with the snake. These are small dogs;, one is a pug and one is a small mixed breed that weighs about 15 pounds. They pull and tug with all their might. Even so, my first snake has no rips or tears. The only thing wrong is that most of the squeakers have given up the ghost. That's why I decided to replace snake. I don't think my pug noticed the difference. I washed it as soon as it came out of the package just to make sure there was no residual die in the fabric as I knew my dog would have it in her mouth ASAP. I don't put my dog toys in the dryer but they just have to be washed from time to time. So, all is well with snake except that he is much louder now that all of his parts work. That's the other thing, don't buy this toy if you can't stand the noise.
