Anybody that has a Harbor Freight/Pitsburg Chock knows they work awesome, as long as they are pushed against a wall in the garage or bolted on a trailer or truck bed. For another $10 spent at Harbor freight you can make the chock stay in place even on a slippery garage floor...
I bought 2 Self-Adhesive Rubber Safety Step Mat squares from Harbor Freight (Western Safety - Item#98858):

Then sanded the bottom of the chock with some sand paper to help the mat stick. Once sanded be sure to clean the surface. I then heated the chock with a torch to get it nice and hot then went over the rubber mat with the torch quick to get the glue nice and sticky.
Once the bottom of the chock is covered in the rubber safety mat you'll be able to use the chock in the middle of the garage without anybody holding it!
Also a helpful modification is to add some washers between the wheel adapter piece and the cradle stop. This helps add stability to the unit. I've left my bike in the chock for days on end without the slightest worry of it tipping over
