Product review (3 stars): I Liked it originally
I've only had it for something more than a week but I like it.  It was simple to set up and appears to give good readings (I only use it for temperature, most cheap humidity meters are very inaccurate).  I had a much more expensive Oregon Scientific gadget of this type.  It lasted about 15 years but it was a pain to maintain (rhyme not intended).  I have hopes this one will not need the batteries replaced as often.

UPDATE:  It started giving impossibly high outdoor temperature.  Their tech support asked what kind of batteries I was using.  I said it was these (AmazonBasics AA Performance Alkaline Batteries) Amazon batteries.  She said that's your problem.  No house brands are acceptable, only well known name brand batteries can be used in the unit.  I replied, okay I have two name brands of heavy duty non alkaline batteries.  No, those aren't acceptable either.  Finally I then said,. I have three name brands of NiMh rechargable batteries.  No, you can't use rechargeables either.  I probably have 40+ AA batteries of various brands around the house but, according to her, none are usable in this unit, and I have to drive to the store and buy more batteries.  Just to top this off, batteries need an expiration date that's 6 years out.  This is absurd !  So, I'm lowering my rating from 5 stars to 3.

PS I would have inserted a link to the Amazon batteries above, but apparently Amazon doesn't know they sell Amazon batteries.
