Very good quality
Set this up with GLA 4DKH solution and it has been super responsive. Im sure all the glass vessels are the same so I think it has mostly to do with GLA's 4DKH drop checker solution. The 4DKH GLA makes is the most high quality accurate 4DKH solution I have used and I have used every single one. I tested the 4DKH with my HANNA instruments tester and its the most accurate 4DKH solution on the market. This is my 4th drop checker from GLA and Im always satisfied.
