After calibrating the pH meter she works great, the TDS meter is OK, idk how to calibrate, but I ordered it for the pH meter, so if the need arises I'll figure it out, seller seems like a chill person, I messaged them thar the package was arriving late (no fault of their own my stupid a** forgot to switch my address) but regardless it was as advertised, box was damaged but it all worked as far as I can tell, ill do business with this seller again 100% recommended seller! 10/10
