Product review (2 stars): One of two works ok, other only half the screen works, & it took a LONG time to ship.
I received both of the thermometers about 5 weeks after I placed my order.  They came by regular mail, with only the barest of protection.  The 1st one out of the only half of the LCD display works (without pressing on it, i.e., the letters show up only if you apply pressure to that part of the screen).  the 2nd works okay, but the instructions on how to make it work are vague & hard to understand - but you can by thniking about what the engineer wanted to say, you can program it.  I really, in all good faith, recommend this product to anyone that I might call friend.  This is number 2 & 3 of these devices that I purchased, and while I paid a little more for the very 1st one (purchased at Harbor Freight, for a little over $10.00 including tax), Number 3 works at cost of $9.98, because number 2 doesn't work correctly.
