First impressions the Box arrived this this morning , it was very well wrapped and labelled , the box is a Mk 1 but much better made ,the collar is highly visible and made of plastic and a good sized Buckle which is a real plus as i have bad Hands and eyes , it works well at 10 Feet + though this was dry testing , all in all its a well made unit and the maker seems to be in the game long term .
