So Far So Good
Been using two of these units for the past couple weeks and they are performing well. Temperature accuracy is as advertised (they give the exact same reading to the tenth of a degree C and these temps match other accurate devices I have. The relative humidity values vary by 0.5%, but this is in the advertised range. Very easy devices to set-up and to remove data..

Great value. Excellent product.
After 2 weeks of testing I'm going to give the OM-141 4 stars. If I could give it a 4.9 I would do that. I've only had one problem so far and it is not a showstopper.
I initially set the sampling rate to 30 seconds to collect and simulate a collection of many data-points, way more than we need), and in one week it had collected more data than the software seemed to download without a 'timeout' error being thrown. There needs to be a way to set the timeout value. When I put these in production we will set the sample rate to 12 hours, more than adequate for our needs, but I'd like to only download the data when I receive an alarm. if my freezers are doing well, I can foresee a timeout occurring if the time between downloads is sufficiently long to record a bunch of data-points.
In device setup, the sensitivity of the slider to set High/Low points is way too sensitive and I end up setting bounds slightly different from what I want. Not a big deal, but frustrating.
As I explore the software I am continually surprised by how many features are available. The best advice I can give to new users of the products is to "Read the **** manual".
Another problem we experienced had nothing to do with the device, but rather it was cockpit trouble: when we placed two of the device, I forgot to hit the start-button. I don't know what the solution would be on the OM141 to protect us from operator (me) error. Add that to your "would be a nice feature to have" list.

Thermometer and RH with data log portable
It takes too long to changes in temperature. I regret purchase. Software to retrieve data is troublesome as well. I don’t recommend it.

OK for low budget
I wish I had purchased the 143. The 141 is hard to tell if it's Power On or Not.

Frequent software malfunctions
Purchased 4 of the base models of the OM-141. They worked the first time, well within advertised accuracy. Additional setups and data extraction work 10% of the time. Package software often has timeout errors even with small <100 data point sets. Frequently wipes data off devices for no reason as well. Manual and setup DVD provided no explanations for these peculiar cases
