Query: Reading Discrepancies

Because I am a little high strung when it comes to accuracy when taking my temperature, I tested this thermometer by measuring my temperature on both sides of my mouth -- every day. Fortunately, when I ovulate my temperature jumps SIGNIFICANTLY, so I am sure when there has been a change. But for women who have less significant temperature changes, I found this thermometer consistently inconsistent with its readings -- even when taking my temp on the same side twice in a row the readings were different enough to be statistically significant for many women.I also had the same difficulties with turning it on and off with the little push button at the end that other commenters had. And the lack of lighting is a frustrating non-feature as well. There are far better options on the market.
