Product review (2 stars): Requires special batteries
I don't like buying batteries as they are expensive, wasteful and polluting so I've relied for many years on the Sony rechargeables. This AcuRite product does not recommend their use and I didn't know that when I bought it here. So reluctantly I bought batteries and was still not satisfied.  I suspect that if it is so picky about batteries that it isn't reporting the humidity accurately as they lose power.  I also note the AcuRite are a bit weasely with their words when they say that this product is precise.  They don't say it is accurate, which technically is different from precise.  The only mention of accuracy is in a tag line which is not a claim of the product but just an advertising jingle.
