    Rare and fabulous transistors, will help keep my vintage TV operating for years to come. They were expertly packed with love for safe shipping and expediantly shipped straight to my front door. I've regularly done business with this guy and he comes through every time. That makes me a very happy customer. Thanks again for the satisfying sales experience and see you in the next transaction!

    Was well packaged, shipped quickly, and was as described. It always seems odd to comment on the value of a purchase of money, since the usual expectation is that it is going to cost more than face. But heck, since money hasn't been backed by anything of actual value since President Nixon hoodwinked the American public, whose to really say what value money has in any situation? Regardless, I am happy with my purchase. Thanks!

    There was a mix up on shipping. Seller issued a full refund and put me in contact with the person that received the package by mistake. Overall , I received the view master reel for the cost of shipping. I applaud the sell on the way they handled the matter and took care of the situation. Thank you for your fast response and consideration.
