These are items I just selected, copy, pasted from my Amazon Orders listings for the last 3 years. Some items have been replaced by similar newer models. Have ordered many more items like my camera equipment and clothing I would recommend to the appropriate audience, however, would have no use for senior forum members so did not include.
