Woah, the fanboi is over the top. If the LR worked half as well as he's claiming, Garmin wouldn't be selling out every shipment of the Xero in days, there wouldn't be a succession of LRs for sale and LR wouldn't have to have had their $499 Xmas sale.
I tried to do a side by side comparison of the C1s to my LR and despite trying with and without a trigger, aiming, fiddling, etc., etc., the LR picked up one shot while the C1's didn't miss a beat, and that included people shooting to the left and right of me. I actually took the Xero up and down the line to let people use it. I just popped it down by their rifle and let them shoot, not one dropped shot. I have no confidence LR would even approximate that reliability, and the Bluetooth is a whole other story.
