Product review (4 stars): Simple easy to read.
After the original battery died, I replaced the battery with the same model CR1130.  Now it is hard to differentiate the different numbers.  All the LCD segments are partially lit.  Only at certain viewing angles can I read the actual temperature or humidity.  Looking directly straight on looks like every LCD segment is visible.  Only at an extreme oblique angle can I read the actual temp and humidity.

Addendum:  Tried the LR1130 1.5V instead of the CR1130 3V and got much better result.  Raised rating back to 4 stars.
