I have sent 1 BCD 436 and 3 BCD 536 scanners to Uniden in 2014-2015 for the original dim light/circuit board issue that was covered under warranty. I wrapped mine with several layers of heavy-duty bubble wrap I purchased at Office Depot. Then put them in a good box and insured it at USPS before it was shipped. I have also sent other electronic items in the mail and always use the aforementioned shipping procedure. I am happy to say that all the BCD units are still running perfectly and have been running 24/7 ever since.
