I have bought at least15 Black Box and Black Box+ from Two Way over the last two years. Have done everything on-line with no problems to report. Once in a while, one gets dropped overboard - but that is bound to happen at a boat yard, but the product works fine, the pricing is the best I have found, and if there is a delay in shipping (which I think happened once), I get a call within an hour! I purchase for a boatyard in RI and we have 12 personell at this location that use the radios every day. This is one of 23 marinas in New England owned by the same company, and I know my fellow purchasing agents buy Black Box from Two Way for thier yards as well. Thanks Two Way for making this purchasing experience a breeze, and my job easier!
