Product review (3 stars): Poor calibration: Even when the remote sensor is sitting ...
Poor calibration:
Even when the remote sensor is sitting right next to the base station, the indoor and outdoor temperatures are off by a degree or two.

Uninspired support:
I called support to ask if I could recalibrate. I was 17th in line. After five minutes or so, I'd only gotten down to #10 in line, so I opted to have them call me back. "without losing my place in line!"  They didn't call back. Approx 2 hours later, I remembered, and called them again. They'd already closed. (Support til 5pm Central) No option to leave a message. Lame. ...To their credit, they did eventually call back that same day. Support was friendly but not helpful.

Poor documentation:
Support told me that my degree or so of discrepancy was within the +/-2 degree calibration present in "all thermometers".
Neither the manual nor product listing mentions this. I call BS, anyhow. There are plenty of more diligently calibrated thermometers out there.

Poor readability:
If the lighting is not perfect, it's difficult to read both temperatures from some angles when only a few feet away.
I would not purchase this item again. I use one other AcuRite item and while it's nothing to write home about, it's okay, so I'm not totally severing consumer/company ties ;)

...But, after living with it for a few months, I added a couple more stars. Why? I got over the fact that it's poorly calibrated. I don't even remember which one is colder/hotter than the other. I've just resolved to be okay knowing I'm somewhere in the ballpark when I look at the AcuRite 00611A3.
