    Exactly what I wanted - Updated
  

*by J***N on Reviewed in the United States on April 22, 2014*

UPDATE: 11/30/2016Over time, the display becomes less and less readable.  This happens over the course of a year or more though.  I came back to amazon to buy a replacement like I planned before.  However, this has tripled in price.  Yes, tripled!  I originally bought this for $4.42 and now it's $15.30.  That is a huge jump and given how difficult it is to read and the lifespan of the product, I knocked a star off since the value is no longer there.  What would have been a simple purchase of 1 or 2 more of these has now caused me to look around to see what else is out there.ORIGINAL REVIEW:This thing works great and does exactly what I need.  How difficult is it for a company to make a thermometer that shows the current temp along with a min and max for the day?  Apparently REALLY difficult since this one and one other one were the ONLY ones I could find on Amazon.  I took a chance with this one to be used inside my kegerator and it has worked great ever since.  It was also super cheap too.  So that's another plus.If I had to complain about something, I would say that it's a little hard to read where I have it set (Kind of hanging on one of the kegs).  But I could probably spend some time and find a better location for it.I might buy a couple more as backups in case I ever damage this one since it has already fallen a dozen times already due to me moving things around.  While it still works great, I'm simply paranoid that one of these falls might be its last because of how inexpensive it was.

    It works, but instruction are inadequate
  

*by D***S on Reviewed in the United States on October 10, 2013*

I usually don't review products unless I can add something to the dialog and until I've used them awhile.  I received two max-min thermometer today.  It is very hard to open the top of the unit.  I thought it would break because I had to exert so much force--cutesy but BAD design.  The instructions are not very useful.  It would of helped if they pictured the location of the "buttons."  They are inside the battery/circuit board compartment.  I didn't notice them when I activated the battery.  After some fumbling around, I managed to get the compartment open again and found the buttons [the roof of the "house" comes off, exposing the batteries and controls.] From there it was very easy to change settings.I'm concerned that when I try to open the compartment, soon or later I'll break the unit.  I can't say anything about accuracy at this point.  The suction cup won't stick to the insides of my upright freezer.  The sides have a very slight "orange-peel" texture.  Three stars may be generous but this is exactly what I wanted: something simple, accurate?, and inexpensive to monitor temperature in 2 freezers used for brewing/dispensing beer.  Time will tell if this was a wise purchase.I tried to find better instructions at the companies website.  This model is not listed anywhere on that site!!  Go figure!

    Working on original battery for over 14 months and still going strong!
  

*by J***S on Reviewed in the United States on October 29, 2015*

I purchased this thermometer 14 months ago.  I put the battery in and am still using the original battery.  It has shown no sign of dying and since there is no power switch it is on 24/7.I cannot say for sure how accurate the temperature is but it definitely serves its purpose which is to sit on top of my equipment rack for all my home theater gear in a dedicated equipment room that houses amplifiers, computers, blu-ray drives, etc.I like that it displays down to the tenth of a degree but I do believe it rounds as I have never seen it change in less than .2 degree increments.The only thing I would change or wish was better was the contrast.It lays pretty flat on top of the equipment rack and every time I want to see the temperature I have to tilt it up just a bit.If it had an adjustable contrast it would be perfect but I still highly recommend.
