Very nice piece for field use.  The only reason I don't give it a 5 is the sharp edges on the case.  If you are like me, I lose stuff.  At this price I can afford to purchase several to keep on hand.  To put on a lanyard you will need a small spilt ring because the lanyard hole is very small.

Also note they are kid tuff too!  My [...] has not been able to destroy mine yet despite near daily use for the past few weeks!
