So far so good. Only a couple hunts with these collars, and they do not drop signal like the DC40-DC50 Collars(Which I sold to purchase these). Would recommend if you were unsatisfied with 40s or 50s while using astro 320.

Awesome collar. Great people to deal with.

Has better range and works better in wooded areas. I was working dogs on rolling hills and did not lose signal.
