I like that it is very precise and for the price it is, that itself is hard to come by. It is a bit larger than I thought it would be but I was able to get used to it. It's nice that it came with a case and also a chart so we can write down our results to get a nice summary. I did get a Low F reading at first but I just figured it meant the temperature was low and as soon as I used it, it went away and started reading my temperature. I do not know that this would be the only Thermometer I use while tracking but that is just the kind of person I am. I like to use at least 2 different at the same time and compare results, if different.
You can find this Basal Thermometer and also this review, here on Amazon.
