I usually like the design, features and quality of La Cross digital products very much, and I own a number of other La Crosse products, including digital wall clocks, digital temperature/humidity meters, and digital indoor-plus-remote outdoor thermometers, and I generally give them 5 stars for excellent design, functionality and performance. However, that is not the case with this particular La Crosse product. Rather, it is worth 3 stars at best, due to the existence of several problems. First, as numerous other reviewers have noted, the instructions (in my case, I tried to use the instructions so that I could find out how to select the appropriate time zone for my region) are very poorly written, and in some places, are wildly incorrect. For example, the hopefully minor and quick task of setting the correct time zone on this clock after having first installed the batteries turns into a bit of a nightmarish hit-or-miss affair since the clock, in real life, does not function in accordance with the printed instructions for setting the time zone (nor for manually setting time and date, if you are trying to do that as well). This caveat goes not only for the printed instruction sheet that is found in the package with the clock, but also the longer and more extensive instruction document that is available from La Crosse in PDF file format. BTW, speaking of the instructions, they do not remind the user that there is really no need to set anything other than the time zone after installing batteries in the new clock for the first time, because the clock will set the time and date via a radio signal received from time station WWVB in the wee hours of the morning. You see, if you are not familiar with radio-controlled "atomic clocks" that auto-update the time and date via radio signals received each night (usually between midnight and 1 AM, but this varies a bit across clock models) from the NIST time standard radio station WWVB, it is NOT at all necessary to set the time and date for your location when you receive the clock, because as long as you are willing to wait until the period between midnight and 1 AM, the clock will set the time and date automatically using the signal received from radio station WWVB. My biggest disappointment with this clock was that the projection unit displays outdoor temperature and the time in alternating fashion, and worse, it always displays outdoor temperature for a 3X longer period than it displays the time. It is unfortunately not possible to turn off the projection display of outdoor temperature so that you can see only the time at all times. Beyond that complaint, there is also the fact, as other reviewers have already mentioned, that the overhead projector display is not particularly bright, even when set on the brightest setting. Bottom line: if you are looking for a good projection clock that will project the time on the wall or ceiling so that you can easily set it at night, there are better products on the market than this one!
