I bought one of the new hanna ph meters, the red one. The probe went bad after 4 months. They sent me a replacement free and I didnt even have to return the old one. Luckilly I bought a bluelab truncheon while the hanna was down. The truncheon is the shit. Best probe on the market. it will cost ya though, but I think you will find it well worth it.
