## Customer Reviews

### ⭐⭐⭐⭐⭐ Saved money and they worked fine.
            
*by J***X on May 24, 2016*

I occasionally use a pH meter just to measure the pH of my lawn and plantings.  Some require acidic soil and other more alkaline.  I had some old calibration buffers in plastic containers ... but since they were old and the plastic doesn't prevent water loss and changes in concentrations I couldn't use them.  I made up new buffers from the packets and was able to calibrate my pH meter.  It was a lot cheaper than buying several different  500 ml of buffer solution.  I store the new buffer solution in GLASS containers.  Since the remaining packets  are dry powder, I don't have to worry about adverse changes that might occur in solutions held for years.
  

### ⭐⭐⭐⭐⭐ Worked as it should
            
*by T***S on July 26, 2019*

Allowed easy calibration of my ph meter.  Don't forget to save the solution for future use.
  

### ⭐⭐⭐⭐⭐ Excellent!
            
*by J***O on July 17, 2016*

Excellent products.  They all worked as advertised.  No problems whatsoever.  When I haven't used my pH meter for several months, it has to be re-calibrated with these buffer solutions.  I keep the solutions in air tight containers and they last a long time.
