I’m embarrassed to say how many meters I have. I was advised as @Bluetit1802 said to stick with one. I didn’t and it done my head in.
I would add to that by saying any unusual reading firstly should be well out of your normal range for that time of day, and secondly, it is probably better to do a re-test with the same meter, and if wildly different, a third test with same meter. That is what I do, even though I have 3 meters. All meters throw up silly wild readings from time to time, which can be a strip malfunction or human error - speck of dust on your finger!
