RE:NCS4 Xonarsafe Review
Don't worry about Evolv. Worry about MSG 30% false positive rate with common bulk in pockets. Oh yeah, you should also ask yourself how you feel about claims of 2" knife detection when MSG can't even reliably detect 4-6 knives. What does it tell you about PE? Believable guy, right? :) Right up there with Safety Act label splattered all over promo materials.
