    Transaction was very smooth and drama-free. No excuses, no issues, no delays, no problems...love this seller. Items arrived very nicely and were conscientiously packed...and they ship to Guam unlike most other sellers selling this same that refuse shipment to Guam because they say we are a foreign country. NOT TRUE! Guam has the same political affiliation as Puerto Rico. We are not foreigners. We are U.S. citizens and we are definitely American. Seller gets it and I'm very happy. Seller is A+++
