After searching the internet for some info on a 8-3160 crane ignition ,There was more than one person that made comments on the possibility that DTT had made the crane unit .Got hold of DTT tech yesterday with the possibility of buying one of their units, if i couldn't get good data on this crane unit.I guess i was disturbing the techs quiet time when i called.If i hadn't been treated so rudely on a couple of simple questions ,i might have bought one of theirs.IF the "gentleman" I talked to had any kind of people skills,he probably would have gained a customer.Instead he lost one and i will now research others and use anything but their stuff.So congratulations mr tech at DTT .You have one less customer to worry you . This happened on monday the 27th of December .To top off the rudeness ,i left him with "have a nice day" .To which he replied ,"yeah" and hung up -----Nice. I have been told their stuff is good ,but i won't buy from a business that has that kind of attitude to a stranger on the phone.Just venting ...hope everyone has a good day
