I got to try them for the first time in Sept at the "Cookout" in Ga. Tim brought a set for us to play with and they do work well.
Now don't tell anyone but I used them on a pellet pooper (1st time to use one) and really liked it.
Talked to Brad and thanked him for sending a set to help raise money for the cookout.
He really is a great guy and will talked to you like he known you for awhile.
If you don't have a set get them you won't be sorry, I have a set on the way
