Has it always been that way I am thinking you have an issue with the one you have. A while back I had looked at all the brands on line and they all seem to look the same, have the same features and offer the type of sensors, Being to think there is no difference in brands.
Had a TST at the beginning and had terrible issues with it. Now have a Hawkshead for 5 years and no issues. Place side by side they looked identical.
