Dentsply Rinn has, IMHO, the best sensor holders for digital sensors without question.  This new adjustable system is AWESOME!  Whatever you are using stop now and use the FIT version.  I haven’t used it for very long and my main concern is the adjustable part wearing out.  However, I am not switching back to the standard Rinn unless the adjustable version starts wearing out like crazy AND they jack the price way up.

I bought it!
