Double checked now I am on a computer herpstats are +/- 0.9ºF. helix is +/-1ºF (0.1ºF is nothing of note) Ecozone is +/-1ºF The DA herpkeeper is the same. The VE series I have been told is 0.9ºF as well but that is not in writing if they would call a unit reading beyond this 'broken' and replace it I can't say it is not spec'd in the manual they there is no obligation to do so.

Here is an image I shot to show IR guns can easily be incorrect, but it shows a 'pile' of thermometers. The one just below my hand is a very accurate scientific grade one it is reading 23.4 (74.12ºF +/- 0.5ºF) You can see the cheap ESU thermometers are basically correct (23.1-23.9) the flukers and zoo med are a bit more off. (hygrometers are stupid bad 94%-21% that is a pinched cord one reading 24.1/94%) The two brass dial types are both spot on (salt test verified) at 50%RH so is the flukers.
