I'm just now setting up my Rhino after some months, mostly job-life stuff, but also I was waiting to see if I can get a VPC MongoosT-50 CM2, which is the one I really wanted.
I was able to snag one on eBay, brand new. Just received it and now when I attach it to the Rhino I get no button presses, none. Grip is totally dead. Pins in the connector all look good, and I'm sure it's seated correctly.
Plus, I have a TM Wartog setup and both the standard TM grip and my add-on TM F18 grip work perfect when mounted on the Rhino.
Additionally, the VPC grip works perfect on the Wartog base.
