You mean it doesn't bother you that it doesn't alert you when you go out of range, doesn't re-register w/ the base when you come back into range, and continues to read the same temps that were displayed when you went out of range regarless of changes in temps since you went out of range.
There is a thread on TVWBB in which electronics experts show where the unit's antenna is supposed to go as well as showing that they didn't put one in most of them. When I sent mine back to them to be repaired or replaced, they sent me someone else's broken used unit in it's place and denied any knowledge of antenna problems even though they aknowledged the problems when I spoke to them on the phone.
IMHO not only a crappy piece of equipment, but an even crappier excuse for a company. You know how they told me they tested them for range?
They walked 30 paces across the warehouse floor and called it good.
