Product review (5 stars): Works well, and at a good price!
I like it! It's bigger than I thought it would be (I didn't check the specs), but that's ok, the numbers are very clear. Outside numbers are larger, perhaps to emphasize that it has an outside unit?

It's reasonably accurate. I have several other temp/humidity devices; the AcuRite is within 2 deg on temperature and 5 points on humidity, exactly what I would expect on a unit at this price point. (Higher accuracy is costly.) The real challenge is locating the outside sensor so it is in the air, away from the house, out of the sun, and protected from rain. My outside sensor got wet a couple of times, but seems to recover after a few hours.

I had some initial problems getting it set up, but my call to customer service was quickly answered, and I finally got the batteries installed correctly (hint: read the manual!)

Update, July 2017:
  Just returned from extensive European travel with this unit. Set it up in dozens of places, always worked well (so long as I could avoid direct sunlight, and rain!). Got the outdoor unit wet a couple of times, but after a day of 99%RH readings it worked ok. Replaced the batteries after a year. Now I got it back home and it still agrees with my other weather instruments.
