^IMO, you left the most important aspect of laser jamming performance: RELIABILITY
If your laser jammer doesn't last in the field because it is either poorly engineered and/or overdriven then its performance (when it works) really doesn't matter and, in fact, you may be putting yourself at risk (especially if the laser jammer doesn't provide adequate diagnostic feedback during power-up).
I have heard far too may complaints from users of laser diode jammers to risk using them myself and again, IMO, any theoretical performance advantage is largely offset by using an LED-based laser jammer with Veil.
That's why I stick the three majors: Beltronics, Escort, Blinder, because I know they will continue to operate reliably in the field after their install.
The added bonus is these cool operating laser jammers cost a fraction of their more expensive laser-diode counterparts.
There has been only one laser-diode jammer that, I believe, has proven the test of time and that is the Lidatek LE-10. Unfortunately its been out of production for some time...
About the ZR4/9500ci, yes that is a very nice feature, indeed, and I believe you are correct, the Blinders do not have the ability (to receive only).
