Product review (4 stars): I wish I could give it five stars
I feel guilty giving this product only four stars. It might work fine but for my drawbacks. I have cataracts and I brought this for its larger display. It is supposed to be back lit and it is supposed to display in F instead of C. Unfortunately the instruction manual is written for Lilliputians with font too small for me to read. I await a visit from my grand children to read the manual and tell me how to use it. I installed the batteries without difficulty.
