I am thinking of possibly buying a Steelman Chassis Ears tool to help try to troubleshoot noises on my truck and anything that might come up on my G35 since some noises only happen when moving. I'm trying to get some feedback about this product and was hoping someone here might have one or have used one.

Does anyone here own one or have any experience with using one? If so, how did you like it and was it worth the purchase?... also.. which one did you get, wired or wireless.

Below are links to both types:

WIRELESS(Can be found for as low as $202 shipped):

If you have one, I'm curious to know how well it works and if they are capable of actually clipping onto large things like differentials, etc.
