I have sent those pictures two times ! re-send me you e-mail and I will try one more time.

Sent the pics to the address you gave me, let me know if I need to send them again

I will getr a few pics your way tomorrow

I have one that I built and it works really well for me. It takes the dogs a while to get used to it, but once they figure out what is expected they do good on it. I don't know how to post a pic on here of the darn thing !
