I posted in a thread about Relion, but it was a very long thread and the post went to the end. So here it is. I've been using it for a year now and replaced the battery about a month ago. Lately, it has just given me a blank screen after I get the blood drop, instead of that flashing hyphen. What do you think could be happening? Do they usually last only about a year? I did everything right and got a good sample of blood.
