Fortunately I replaced my 10+ yr old helmet with this strong lightweight helmet a few months ago, two weeks ago crashed when I stood up to get increased speed and my shoe clip slipped off the pedal and my handlebars jerked to the right at 20+ mph and I had been thrown off and sustaining with my right clavicle. Thank god I didn't hurt my head with this helmet...no concussion...the helmet was intact! And it automatically sends an SOS alert to my family, which helped me a lot.
In addition to its protective function as a helmet, it also supports clear conversations with the built-in wind resistant microphone&stereo speaker.
Highly recommend.

I am an avid mountain biker and at 34 suffered a severe traumatic brain injury. I had to park the bike for 2 summers. Now that I'm back in the swing of things I started researching helmets and impact ratings. This helmet for the price is amazing.
It's very durable, adopts integrated molding for superior impact resistance, and the absorptive capacity design makes the helmet more airy and comfortable for riding. The extra long endurable battery makes a great companion for long-time use.
Customer service is also A+. I highly recommend this product for anyone and especially if you have suffered a head injury. Worth the money.

1. Speakers are low quality - it was not meant to be best speakers for music, but while riding it's perfect - you hear you environment and some music - they are loud
2. Microphone could be better - but it's ok
3. Lights are bright - you can change flashing modes
4. Communication in group - works well
5. App is good
6. Remote controller is good

Overall rating 4/5

I purchased two helmets because I needed to communicate with my husband during our rides. Pairing them was super easy and then pairing with our phones, also very easy.
