[Q]: A cool concept unfortunately marred by poor build quality. The leash holder that's supposed to spin to prevent the leashes from tangling doesn't actually spin unless you apply more force upon it. Often this will end up having the wires wrap around each other many times over forcing you to stop, rein your pups in, and fix it. This also can prevent you from pulling in your dog or locking the wire since everything gets tangle quickly. Overall a nice idea but it might be better to find a more qualified manufacturer. This gets 2 stars for messing up the key component that's supposed to set it apart from other normal leashes.

[Q]: We have 2 machines and both dogs eat a medium size kibble so the machine should not have any problems. One of the machines seems to work decently well while the other has had problems with kibble jamming and no food is deployed. Today is only the 34th day in use, 4 days after the return period has ended and now the motor on the one that has been jamming completely died. The feeding time alert came on and the motor never kicked on. In the past when it would jam, you could hear the motor turn on, but no food would be deployed. Today, the message came on, but the motor did not.
[A]:
Not dependable, chronic jamming, motor died with only 34 days of use
