      Thank you Jeff for taking extra care packing the Sig Sauer ASP20 , and shipping it expeditiously. It’s in excellent condition as described, and I believe it is a great value for the rifle, scope, packaging, insurance, and most of all the communication. I also appreciate the knowledge you shared with me. I hope to stay in touch with you in the future. I will be watching your items. Thanks again. Stan

      I purchased both a ti 15 and an hp 28s, and despite the later being ten times the price, the same diligent care was taken in the packing of both calculators, which showed up exactly as described no doubt thanks to said packing. Shipping was prompt and the seller was very personable. I would absolutely recommend this seller

      As Gracián, a 17th-century Spanish writer, said, “Good things, if brief, are twice as good,” so I will only say that the calculator is exactly as it appeared in the photos and as described by the seller, a 31-year-old object that do PS for Ebay: The website, at least in Spanish, has an error and does not allow questions to be asked to sellers. This will prevent some purchases from being made due to doubts that cannot be clarified because it is not possible to speak to the sellers.
