Mine came with 3 calibration fluids 4, 7 and 10for more accurate alkaline or acidic testing, also the case was a big bonus, my first meter came with nothing. And you dont even need the storage solution unless its being stored long term. It actually says if you use it more than once a week you only need to put distilled water in the cap! I absolutely love my apera, wish I would have just forked out the extra 20 bucks when I bought my first meter, its a night and day difference in quality and accuracy.
