I just received one, and am impressed with it so far.

When I fired mine up, I found that the humidity was off by 10%. Luckily, you can put in an offset in the app, so I put in -10 and it matched the others fairly well as low as 30% RH and up to 90% RH. I think that the offset limits the maximum that you can measure. For example, I put the probe inside the humid hide, which was 95% per my other meters, yet the Inkbird would only read as high as 90%. I guess the limit is probably 100% minus whatever you put in as the offset.
