Odd - I have had a few of these and this one seems to not want to work in direct sunlight. I tried it with the included batteries and it reads "Finger out" and turns off. I tried with fresh Duracells and it reads "low battery" then turns off.I went indoors and was packing it up to send it back and tried it again with the included batteries (AAA) and it started working. Went back outside and "finger out" popped up again. So, it's very light sensitive.I went back inside and tried the Duracells. Still showed "low battery" even thought they tested fine in a voltmeter. So, there is something about either the fit or the output of the factory batteries that tells me once the supplied ones are dead, the whole device is dead. Perhaps lithium versions would drive it.It also does not have any orientation options. My others will rotate with each button push so you can read it rightside up regardlass of your position. This one only has a single display orientation.There is a menu where you can alter the brightness and the 10 second auto off feature is nice but off the three I own, this is the lowest rated. Head to head with the others (one on each finger) it is +/- 2 on all readings, so roughly the same accuracy. I would have sent it back, but this is one that requires you to print and box unless you go to Whole Foods and that drive would cost me more than the device is worth.

Teuer aber relativ genau und gute Ablesbarkeit
