Smart Motor Mounts - how to use them?

Anyone use the smart motor mounts? What are the benefits of using them? Would love to see some pics.

There are two types in the pack - one that allows you to connect pins to the back of the motor as well as the shaft side. The other allows you to put two motors back to back and support them in the middle. A good example of this is on the standard Clawbot and Stretch models. The fact that the backs of the motors are not connected together means the chassis is not a rigid as it could be.
There are some pictures in the link below that show you how they can be used.
