Great Calibration
I like using these powdered calibration packets, they are simple and straight to the point. You don't have to throw them out after 30, 60 or 90 days like the liquid calibration solutions tell you to. All you do is pour each packet into a cup with 250ml of distilled water, make sure its dissolved, insert the pH pen and hit calibrate. BOOM! Calibrated. Easy peezy, lemon squeezy! Highly recommend these packets.

Worked great
Using a powder buffer solution is more tedious and annoying than a premixed solution, but this does a great job. The only issues I had was when the water temp was too cold for the powder to dissolve properly.

Excellent customer service
The team was very adamant about ensuring that my pH monitor was satisfactorily calibrated... while the first few powders they sent did not dissolve properly and appeared to not calibrate correctly, they proactively reached out to verify it was working (without me even issuing a complaint) and sent replacement powders for free. The first set of replacements did not work, so they sent a second set of replacements, which worked well and calibrated my pH monitor as expected.

Exactly as described
Product is exactly as it is described to be. I actually took small water bottles, mixed a solution in each one and used those 3 bottles to calibrate my PH meter for over 5 months ths without the bottles dropping or rasing in PH.

Great value.
These are always accurate and you can store the solution in a cool dark place for months on end. At roughly 75 cents a pack to make 250ml its cost about $3 to make a litre which cost $14.99 at the hydroponic store. So you save $12 mixing your own.
