Me and a few other friend just got 5 Smart tester for PO4, 2 is up running, and it’s still less then a month old. We are already having issues with reagent 2. It got a much thicker consistency liquid, and keep getting the pump can’t add reagent failure messages. Both Smart Testers that are running have the same issue. I’m surprised no one else has the same experience, and 2 out of the 5 units we have this same problem. Once we get this error, the accuracy goes down as well.
We also bought 10 reagents packs, and 5 out of 10 reagents packs have leakage problem upon arrival. Very poor packaging.
