I just wanted to take a moment and give a Hewge Shout Out to Bart at Big Boys Hobbies. I just received my Gray Ghost NDT headphones on Saturday after ordering them on Wednsday morning. Bart, as always was helpful in any questions and expedited the shipment. I have talked to Bart on line on the BBH website several times in the past, and Bart never fails to answer any questions you might have, most times right away on the chat forum. This was actually the first time I have dealt with BBH, but it certainly will not be the last. Thanks Bart and Well Done sir from one satisfied customer.
