It is a generic brand. Here is a link to a place where some Advocate products are sold:I'm not familiar with the Advocate brand, but welcome to the forum, and I hope you find the information you seek, leafs.
How expensive are the strips for the ReliOn Ultima?Sorry about that, leafs . . . the meter I use is the ReliOn Confirm from Walmart, but there are dozens of others - some more expensive, some less. I use ReliOn because it's as accurate as anything else, but the strips are about half the price of other brands.
As for the life of the strips, I used the ReliOn Ultima for a couple of years and the strips for that model were packaged individually in foil wrappers. Those would definitely last longer under adverse conditions than ones kept in an open container. And I liked the individual wrappings because it removed any risk of contaminating the strip by touching it to insert into the meter.
