My personal experience with the Relion A1c tests has been...
Yes, check the expiration date on the box. I have picked up one that expired but it was just 15 days over so I used it anyway.
The testing I have done seems to closely agree with the tests my doctor gives me. They are usually within .2 difference.
The A1C test is subject to a .5 error in either direction so a 5 could be anywhere from 4.5 to 5.5
My goal is to get an indication as to how well I am managing my diabetes and I pay more attention to trends from month to month rather than get too hung up on 1 particular test (similar to the morning fasting readings).
It has taken time but I have learned to not get too hung up on individual readings. Diabetes has many mental components and one of the largest ones is that it is the long game that has to be played and the trends are much more significant that any short term readings.
For example - Thanksgiving I had a traditional dinner with stuffing, some bread, corn, and mashed potatoes (all no no's). The only good thing on that plate was the turkey. I am sure the gravy had flour too lol... Not surprisingly I tested at 170 a little over 1 hour after eating. This prompted me to spend the afternoon on a 20+ mile cycle rid to burn up some of that. For all of November, with that exception, I followed my regular diet and exercise plans. My doctor tested my A1C as a regular diabetes checkup and it was 4.4. The at home test was 4.6. Not enough of a difference to quibble over. So while being at 170 that one period horrified me, we can see that it didn't affect my A1C too much. This is a perfect demonstration of how just a great A1C does not necessarily equate to good control as short spike will not have a great effect.
My goal is to stay under 5.5 so, either way, I am very pleased.
