Product review (4 stars): Could be improved ;-)
Reasonable value for the price!

Comparing it to my multitude of thermometers it seems accurate - but as we use the [coarser] Celsius scale in OZ, I might suggest displaying a further decimal place. This being the case for my other units.

Placing both parts inside, & next to one another over an extended time, I was a little disturbed to find that the 'outdoor' humidity was registering lower than the [more accurate] indoor. Presently 36% ('outside'), compared to 42% 'indoor'.

As might be expected, the smaller mass of the outdoor sensor seems to allow it to react more quickly to atmospheric changes.
