Personal Update:
On Tuesday, I have picked up my "price beat" bargain Neotec 2. Fitted previously purchased SRL Mesh comms, You only have to remove the cheek pads and plastic covers on either side and a battery compartment cover followed by the foam that is filling in the void.
Fitting comms, and pinlock overall took around an hour with a bit of glancing at the instructions, being distracted by the conversation from my wife. Anyhow, I recon once can get it done nice and neatly in around 30 minutes. It is certainly easy enough to do.
Yet to wear the lid in anger on the road, but quality of speaker is a massive improvement over my Sena (for Arai) 10U version.
