EZ-900This holster is made for the E Collar Technologies EZ 900 remote. The holster covers the buttons that are not needed and has clear access to the buttons that are. There is positive retention built in, so you actually feel the remote "snap" into place. The second retention system is the bungie retention strap, with a pull tab on the bungie to make it easier to take on and off. The holster has been tested in the field by actual K9 handlers. They
