Product review (5 stars): Bought For The Unique Dew Point Feature...Excellent Price And Performance So Far...
I have to admit I bought this All-sun hygrometer simply because of its price...I have never had any use for the humidity reading on one of these.  I got it for its unique dew point feature...For some odd reason, weather people, stations, and even weather sites online tend to ignore the all important dew point which more than anything else relates what it really feels like outside, (or in) as to it being comfortable...Unlike a humidity reading, the dew point is never wrong, or misleading as to comfort.  No matter what the temperature is, or humidity, if the dew point is high, its muggy and crappy out.  If it's low, its dry and comfortable.  Unfortunately, even the instrument manufacturers haven't caught on to the significance and importance of the dew point.  This piece like all others displays the humidity as the prominent reading, with the temp and dew point being smaller.  But as long as I can see it clearly which I can on this I am very satisfied...This was a cinch to set up with the enclosed instructions.  In fact the only thing I had to do was put the batteries in it and then switch it from C to F which you have to do on everything these days.  The readout is big, very clear, and has excellent contrast.  Although it includes a sensor that can be detached and remotely set, like outside a window for example, I have this right on the unit for I like knowing the dew point in my home.  Fortunately this mounts easily on the wall, (not all of them do, and some not at all), and I had the perfect location for it...

In conclusion, I can well understand depending on some peoples needs and circumstances why a humidity reading is very important.  Humidors, wine cellars, etc...But for me I am interested in the dew point reading, and this unit does that for much cheaper than any one I could find on Amazon at the time of this writing.  It's big, user friendly, and the cost can't be beat.  It's too early to tell if this will be as durable as I hope.  So far it's doing its job flawlessly.  But if it up and quits for any reason in what I consider an unreasonable amount of time, I will certainly be back to update this review.  For now, it is so far so good, and I give it a solid 5 stars, and recommended it...
