Its as big as a zippo light,just about the same size,and the thing amazes me.I on the 5th highest hill in Missouri,and i can hit repeaters 30 miles away in my house with rubber duck antenna...It is a nightmare to program without software and cable,but for 60 with shipping,ya cant beat it with software and cable...will by one for son and grandson soon...i would give it a 9 out of a 10...and also have dropped it twice and once was going into basement and it hit the concreat...73 de JW late note,it has a flash light mode also...hehe
