I have 4 bluelab guardians, absolutely top quality, long-life product. I hear their truncheon is good too. Well worth the price...keep the electrodes wet at all times...few mins to an hour not wet will be ok, but not days..if you can swing the cash, a pH controller may be your next step. I invested in a $300 one from bluelab when I upgraded to a trash can for my reservoir. Never have to fuck with it again once the nutes are in. Early on it did take some calibrating, how much pH fluid to drip each time, etc etc.
