STANLEY Infrastructure knows what you look for in a small mounted breaker, that’s why our MB series focuses on simplicity, easy maintenance, and powerful breaking performance. All MB breakers have only two moving parts – which means better performance and less frequent service intervals. At the lower end of the housing, we added steel reinforcement to not only protect the housing, but to protect the power cell and keep operators running longer. A superior valve design allows for a wider range of pressures and flows. lowering stress on components. Plus, the light tool weight contributes to a broader carrier range.
Features:
•Advanced breaker design technology for output energy and efficiency.
•Minimal moving parts, only two for less maintenance, better performance and less service.
•Superior valve design for operation within a broader range of pressures and flows with less heat and stress on components.
•Added steel reinforcement at lower end of housing to protect housing and power-cell.
•Side-plate bolt locking system keeps bolts from loosening.
•Lighter weight allowing choice of smaller carrier.
•Supported power-cell by rubber cushions and urethane wear plates to absorb shock and vibration and reduce wear - MB556
•Direct acting nitrogen chamber boosts the power of each hammer blow.

Smells too strong
Size: 5 in
My dog hates the way this thing smells. She tries to play with it, but the scent is too strong for her nose. I know it's the scent because she usually sniffs it two or three times in between trying to grab it with her mouth. She treats it like an explosive in her mouth and quickly moves away after spitting it out.
She used to have a bone that looked similar to this (same material) that was unscented and she gnawed the hell out of it. My sister's pitbull spent the night and chewed that toy into bits, leaving my Yorkie mourning the loss of her once treasured bone.
Please make an UNSCENTED version of this toy!!!!

Perfect puppy toy!
Color: Pig Balls
The best puppy toys! These will have your pup happy as can be and well worth it!
They are extremely loud so fair warning but bringing joy to your dog makes it worth it.
Durable for a dog who doesn’t destroy things. Size of a clementine

Puppy loves them!
Color: Pig Balls
I boutgh this for my foster puppy that loves squeaky bouncy toys and she LOVES them, she carries one with her everywhere. It is great to play fetch or for her to play by herself, it keeps her occupied. For reference she is a 7m old 30lb Heeler/Pit mix and very much a puppy chewing and ripping everything off. These have hold pretty well, we've had them for a few weeks now and they are still going.
