CK Tech was awesome to work with! They did our sound and paging equipment at the New Bretz RV & Marine in Billings. We also had them install a high resolution camera system. What a difference there is in systems available... The one they recommended is crystal clear. Doing an install like this during business hours had me a little concerned, however we hardly knew they were in the building. They cleaned up as they went and never left any sign they were ever there. Their service has been top shelf!
