+4 pts“I just did the reverse. I gotten rid (returned refunded) of my 20 - day old R4 and switched over to V1G2. My R4 GPS fried after firmware update and I tried every trick in the pony playbook but nothing worked. It took CS 2 weeks to reply my first email, with an answer lifted of the IT Squad meme. V1G2 has no GPS, so no such issue. Opened the box and installed it, coonected it to their APP using BT, the update just popped over without any intervention. Has been hooking it up to JBV as its control unit from my android and works like a charm for me so far. JBV does the muting based on GPS POIs, etc. And, the suction cups of my R4 fell off after 1 day use. The V1G2 has been stuck for 1 month. Same setup trick, use saliva. YMMV”

Best praise vs top criticism for Valentine One Gen2
Best Praise
+102 pts“I have been driving by that sign for some 30 years with both generations of V1s. With the Gen2 I have become so brazen that I don’t even take it down from top of my windshield even when I am at my sister’s family home in Fairfax county. Once I saw Vortex’s video of him using Spectre RDD I realized no cop is ever going to go through the trouble of pulling you over when there are so many cars around you. And with invisible detectors like the Gen2, the cops can pound sand. It’s like fishing above the ocean with a shotgun.”

+6 pts“I had the Gen 1 since the mid 90’s. Converted to Gen 2 a few years ago. I still miss the volume knob. I could manipulate that in the dark without having to even look at it.”
