When considering performance I look to the datasheets because I certainly don't have the precision measurement equipment required for real-life experience. But, to add a fly to the ointment, there is a very similar deice, SHT35-DIS from Sensirion to consider also. The only real-life experience I have with it is the commercial humidity/temp meter I have, model 01139M, made by AcuRite corp that contains that Sensirion device. It's still working after almost two years and no battery changes. I took it apart to see what the sensor part is. Otherwise, I wouldn't have had any idea.
