I got this just before going on long trip abroad and could not thoroughly test it. When I came back and tried it out, the impeller got constantly stuck, producing clicking sounds and of course recording much too low wind speed readings.I contacted support and was told to nudge it away from the casing, but I could not even tell where it touched. To get a better look I decided to remove the impeller from the instrument, which is normal procedure for replacing it and described in the manual. It came out and fell apart as you can see in the photo. It is a really cheap looking frail plastic part.You should know that they sell replacements for between 30 and 40 Euros including tax and shipping and it is supposed to be calibrated in a wind tunnel and come with a certificate. This is absolutely ridiculous. And it also proofs that it is not made to last. Why make it so easily replacable otherwise?Support told me to send it back to Amazon (which is not possible anymore) instead of offering at least a free replacement impeller. The only thing Kestrel is good at is marketing to sell their cheap quality product for a ridiculously high price.

Nothing to complain about with this weather Meter. Well built, accurate and easy to use. Still learning how to log and graph my readings though.

This guys are awesome. The kit is too!

Got this to use when in the field for Search and Rescue missions and when we need to call in helicopters for the rescue. The meter has a wealth of features above and beyond what would be needed in these situations, but all worthwhile because you never know what you'll need the next time around. It seems to pair quickly with my Note 7 and the Kestrel app that you can download for free. The app seems a little anemic, but I'm not sure how useful it would really be if you're actively using the meter.The meter comes with a little weather vane attachment that lets you mount the contraption to a 1/4-20 thread, like on a camera tripod. This is actually a nice addition for "longer term" use like if you are stationed at a check point and have to relay weather information on a regular basis. You could set up a tripod, mount the meter to it, link it to your phone, and the run the app and record the weather information as needed. Also, it will then give you a true wind direction and speed and not be affected by your body as you hold the meter.I'm glad I purchased it!

Very good product for storm chasing and etc. tracks pressure inside the storm, wind speeds, and etc
