Volume is not an issue. There are some list which are a little less money but this one doesn?t have a 45mph warning. It wouldnt provide any warmth in cooler weather, either. This has two Qi charging plates NOT three. so I added some Loctite to the threads as I assembled, so I wouldnt have to be climbing my sailboat mast to tighten loosened allen screws ! I would recommend having someone help lift an adults bike up to it. Disclaimer: Im not an audiophile, nor do I claim to be one. I?m looking forward to using my new gear! Well made and great entertainment value. It does exactly as advertised and is super comfortable, I could wear this all day.
