The sandals are so cute, but unfortunately came too small for my two year old sons foot. Since the base is so light, your bikes will want to tip over unless you bolt the mount to the vehicle (I use it in multiple vehicles, so this is not an option). Bottom line - not acceptable at the cost. Calidad sonido Serviceability:I?m only calling this out because the original Onyx Studio 1 had both a removable grill so you could see all the speakers, as well as the ability to open up the body and replace any component, including the failed rechargeable battery (which I replaced while reviewing this lineup). Temperatures have been below freezing and I dreaded even driving to the UPS store to make a return. Voices were clear during meetings. I was disappointed because parts was not complete but however I was reimbursed. First pair of Milanos, but have been wearing Brikinstock for about 10 years. Sad but true.
