Has anyone seen these..Utility Dolly for dings

[JaySong]

Hey you all.
We all have few door dings on our cars and places like Dent Wizards charge $75 a ding. someone said they use a metal tool that they message with.

Well, I saw this Utility dolly (a metal anchor looking tool), I saw it at Kragen and Pep Boys.

I got this idea that this We can use this tool to get out those reflection dents.
HAs anyone tried this?

utility dollies are used on the underside of the metal while u hammer the upper side (in body shops... i work there).
however i guess u could use it to massage the metal but u need to be accurate with where u place it.

so no one has any input on this?
