Yeah, I still bought the thing even though it had some bad reviews. I have had very good luck with it and this will be going on my third year of use with it...
I know the temperature gauge works on it as it compares well with my other thermometers. The big question is if the DO meter is accurate. It sure is fun to go to local ponds and lakes and drop the probe to the bottom and test the clarity, temp and DO at different levels. It has really helped me with the fishing.
