Won't hold calibration
The product only last maybe 3 months and that's being generous. After I noticed it was considerably off from my other ph tester, I tested them both and my other one was dead nuts and the one in the picture here was about 3 off. So I had to buy calibration solution never ever have I heard of 6.86 calibration solution so that's what I got calibrated it and tested it, it was worse than when I started. Save ur money!
