For reference, this Nikon branded device is EXAKT the same as the WeatherFlow anemometer found here: http://www.amazon.com/gp/product/B00E9AF7ZU/ref=s9_simh_gw_g86_i3_r?ie =UTF8&fpl=fresh&pf_rd_m =ATVPDKIKX0DER&pf_rd_s=desktop-1&pf_rd_r=0ZS4VKYVEJ7WCNFME83A&pf_rd_t=36701&pf_rd_p=2079475242&pf_rd_i=desktop The only differences are the color scheme and the WeatherFlow block costs $6 and changes more (at the time of writing this article). What I bought is a branded Nikon. BOTH devices work seamlessly with the Nikon SpotOn app and the WeatherFlow phone app (I have a Samsung Note 4 if it's worth it). I carry my device in an EDC bag so I want to know what the wind speed is at all times. This, or when I'm at a shooting range (or deer hunt) and want to know how much side balance I need to make, it's an easy, quick, and accurate way to determine. And because it's small, light, and comes in a stylish carrying case, it takes up very little space in my bag. All calculations are done with my phone, which I always have with me anyway. So why buy a device that essentially duplicates the computer part? Save weight and space by buying this. One reviewer complained that the app needs to be running before you attach the anemometer - while that's true, it doesn't bother me in the slightest. I have to insert the key before starting the car and it hasn't bothered me in the almost 40 years I've been driving - I'm sure running the app before plugging in the anemometer won't bother me anymore. Interestingly, the WeatherFlow app doesn't care which order you launch the app and then plug in the device, or vice versa. Anyway, I don't think launching an app before plugging in a device deserves three stars, but I am. "Not well suited for use as a standalone anemometer." I didn't have the manual either, and I don't need one either. This device is sold as an add-on for the Nikon SpotOn app, which is itself an add-on for SpotOn scopes. This is self-explanatory. And if you want to use it as a standalone anemometer, use the WeatherFlow app. Again, a one star rating for not understanding the product is unfair. If you want to buy such a device, buy it - you can't go wrong. If you want to save $6 and make a change, get a Nikon branded device because it's the same. If you want to spend $6 more, buy a WeatherFlow block.
