Good quality product.

The product looks well made but I would need a working link to download the software. Thanks a lot.


Overall, the unit is a great value (features to price). The barometer has tracked perfectly with a nearby airport since I bought it. The wind speed (when compared to a more expensive device) tracked perfectly (and with shocking precision). Users need to understand that you can't walk from indoors to outdoors and get an immediate accurate outdoor temp. You need to let the unit acclimate to the new environment for precise readings - but again, the device tracked accurately with other gear. I've done limited testing on the dew point, but the few samples were all accurate. I don't believe I fully understand the ALT (presumed altitude) capability - so it is the only aspect I dislike (the manual is useless on this point). It came with a neat little carrying case (unexpected). Overall - I think this is a good deal!

I am not sure if it is accurate or not, I have nothing to compare it to. But for balancing my HVAC it worked because I went by its readings for everything so even if the actual CFM is off (and I'm not saying it is) I went by those readings and percentages and it worked great.
