I use my Unication pager on a daily basis, and with a day job of outdoor construction and towing at night along with emergency services my pager stands the test. Battery lasts all day and works better in most areas than my 800 portable. Very durable, reliable, and rugged. I've landed on my pager while hooking vehicles and been in all kinds of weather with It and wouldn't ever choose another manufacturer. Unication makes one heck of a work horse pager.
