The backpack attachment clip sounds amazing. I'm a recreational GoPro enthusiast with a few blogs/sites. One dedicated to my love of bulldogs, another about wearable technology (had a Pebble since launch and Apple Watch since launch) and lastly a site dedicate to technology incorporated into fitness. A few friends are trainers so we're always filming workouts, sports and general fitness activity (think workout tracking, sports headphones, etc.). I live in Washington, DC which is a great backdrop with the historical monuments, city and surrounding parks. I'm 33, extremely active and adept at reviewing products. I've got an Amazon prime account and often review products (both at the request of the manufacturers and when I genuine enjoy a product beyond expectations).
I would love to test out your product.
