I am amazed. I just turned it on on the radio function at the shop and am VERY impressed. It has a decent equalizer to increase the bass, treble and mid range tones. The top lid is a little goofy. When you retract the clips (two per side) it doesn't pop the lid up and release it. It may just be the fact it's new and sticks. In order to release the yellow lid, you have to release one side, pull up the lid, then release the other side. Initial take on the side mounts: there doesn't appear to be a positive detent or locking mechanism. The weight of the radio and the light rubberized overmold will most likely hold it in place under most driving conditions. Again, the sound is INCREDIBLE on the radio setting. All my 20v batteries I had with me for the day are dead, so I am charging one up to give it a good test. On full volume, the sound isn't distorted at all. Very very clear. I AM IMPRESSED.
