I’ve used a ReliOn Prime before, but I have not done any #samedrop testing with one. The only thing I can say about its accuracy is that it doesn’t list the more granular result bins in its literature. Typically, meters and strips will show test data on how many results from a specific lab test fall with +/- 5%, 10%, 15%, and 20% of the reference value, even though the first two or three of these aren’t required. The ReliOn Prime, on the other hand, only shows that a sufficient percentage were within +/- 20%, which makes me wonder why they chose not to disclose the rest of the data.
Of course, the real answer is that, if you like the meter—because it matches well with your labs, because the price point is good, or for whatever reason you deem to be important—then it’s the right meter for you.
