I needed urgent for my K2 winter expedition. I was on the last min and needed the goods to be sent in Iceland. Their chat online worked 100% and I was able to add on one extra peace even after I checkout. They send with UPS same day and I had the package 3 days later here in Iceland. Extreme Meters works and has good service. I recommend them.

I ordered the Kestrel 3550FW meter. Received email notifications reporting the progression of my order up to delivery, which was much quicker than I'd expected. Couldn't be more pleased with the product and service.


Wildland Firefighter

Great customer service! Quick response on questions and fast shipment to Europe! These materials are the best! A very satisfied Belgian customer. I'll be shopping with you again. Thanks!



The service was prompt and cordial. The Kestrel is used to measure wind velocity and temperature when applying pesticides for agriculture crop production. It is also used to measure weather conditions for livestock comfort.
