Comments: This product is great. I had little idea how much the temperature and pH of my 32 gallon reef tank fluctuated over the course of a day. This instrument has allowed me to focus on stabilizing the tank conditions. pH chemical testers and little thermometers just don't cut it. I'll never be without this instrument again. It's well worth the cost. Yes, I would recommend this product to my friends.

Comments: I like the tester and it is very accurate, however, when it arrived, the calibration was off. The instrument was shipped without a means to calibrate it. I later found a packet of buffer solution to calibrate. One must hold it in solution for about 30 seconds to get a stable reading.Don't forget to purchase the calibration packets and the cleaning solution during the initial purchase. Instructions are minimal at best. No more test strips for me. Yes, I would recommend this product to my friends.

Comments: Very easy to use day-to-day, but the programming (resetting the temp to Fahrenheit, calibrating, etc.) is difficult to follow. Yes, I would recommend this product to my friends.

Comments: This thing is pretty nice!! Do get some extra calibration buffers for peace of mind. Waterproof so I can just clip it on my overflow and with .05 accuracy you can watch you PH slowly climp up while kalkwasser dosing. Temperature gauge is nice too. The only bad thing is , it proved my coralife didital thermometer was off by 3.9 deg. Time for a better thermometer!! Those things are junk! Yes, I would recommend this product to my friends.
