Great news! The new and much anticipated Bel STi-R radar detector has arrived! We have them in stock and ready to ship.
The STi-R is an installed version of the popular Bel STi Driver. Like the STi Driver, the STiR doesn't "leak" a signal and therefore cannot be detected by any police radar detector detector (RDD) like the Spectre. I have not seen any independent STi-R reviews as of yet, but it is expected that the performance will be in line with the STi Driver, of which there are several reviews.
