When driving with two kayaks on the car you could see the kayak on this rack shook a lot less than the other brand,. Received and it was rolled up in a box. The Allys still do a great job of NC and i think would satisfy most people. The voice through the microphone actually didnt sound robotic to the other caller. I would definitely recommend changing the EQ setting when you get them, I am fairly picky on sound quality so out of the box I wasn?t blown away. AND . When the case is fully charged, all the little teeth lights are lit up blue. Also, this charges with the case on on both of my charging mats. HAPPY MEEE! The waist trainer does exactly what it is made to do.
