Gumstick Flex from August 2019, but starts with 090 instead of 101 (one month early). Why did they remove the beep?
I have a new southern California FasTrak switchable, and it does not beep (it's not supposed to, either, per the toll agency: no battery, no piezo).
Ah, that's interesting. I've never heard a beep from any of my transponders, including crossing bridges. Is yours the "gumstick" one? (Thin rectangular one). A beep would be a step in the right direction (but doesn't solve my other grievances).
I have a gumstick Flex from 2019 and it beeps.
Mine beeps but it is an ancient model that is quite large (maybe 3 inches by 3 inches - square)
