Loss of accuracy after third use

I bought this device and salinity refractometer at the same time. After the third use, it no longer measures accurately and comes without a calibration solution. Even with a recalibration solution, the recalibration process is a little intimidating. Buy a handheld refractometer and save time. If you want the digital precision this offers and are willing to frequently recalibrate it, this might be for you.
