I bought this helmet 3 years ago. One of the selling points at that time was the inclusion of the ANGI. I ride solo 99 percent of the time all over the country. Should something happen, knowing that my girlfriend will be notified immediately of exact location is a great stress relief. Fast forward to today. While on a typical morning ride on familiar roads I encountered Eddie, a stout female pit bull with a full-on rage against cycling and no restraint. I was broadsided by a near 100 lb raging dog doing 20 mph on a rural country road. The resulting time and space conundrum found me on the ground in milliseconds. I am ordering a new Matching Propero 3 Helmet today without the inconvenience of a concussion. I'm sore, torn, bloodied and bruised, But very much alive and able to finish the ride under my own power. The helmet is toast, busted in three places, but it did exactly what it was supposed to do, keeping my grey matter off the pavement when it was needed most. Thank you Specialized.
