I've seen quite a bit on the cozmonitor and whether people like it or not, but I'm wondering if anybody else has experienced actual technical problems with it. I get low battery messages and system error alerts half the time when I try to test, even 1 day after replacing the battery. I got so frustrated that I went back to my way-old (pre-Flash) Freestyle for a while. I've been trying to use the cozmonitor again recently, and its the same - low battery alert or system error, sometimes both at the same time...other times it won't even recognize that I've put a test strip in and it'll go back to the stand-by screen. Has anyone else had similar problems? Thoughts? Thanks.
