I bought the 4.0 and the 7.0 and they work just fine but, I was a little disappointed to see that these bottles have to be used up within 3 months or discarded once they've been opened, (according to the label anyway). While I use my Bluelab meter a lot, I don't use it nearly as much as some people do, it seems like overkill to calibrate my meter often enough to use up these bottles in that time.
I guess I'll have to look for smaller bottles next time I need some.

I would've brought the Atlas solution combo it was cheaper . Since it didn't go though , the price on this was great . I brought the 7.0 @ the grow store , you don't use very much so you get your money's worth . It's used only once a month it'll last 5 or 6 months @ least

I use nothing but Blue lab for all of my Ph and PPM/EC monitoring and love their consistent accuracy. Got to take care of your equipment and it will last much longer. I use nothing but BlueLab supplies.

Just what I needed. Exactly what's advertised is what you get.
