Great product, customer service is awesome I had a plastic that came broken the company reached out to me as I ask for a refund they offer a replacement so I accepted the replacement ,everything came out new no broken parts easy to assemble, just happy over all, and with Amazon as well . Thank you, 3M. but I never took into consideration that it was a wide fit and forgot that they generally come up larger on a wide fit so I was diss appointed , as the shoe was really comfortable and Hard wearing ,. This mouse is top of the line, yet budget priced. For $40 I thought the sandals wouldnt degrade so fast. So if your brick line is flush or not a standard size these probably wont work for you. Ive given them to 30, 40, 50+ year old people. Im not expecting that level of quality from a set of $2-300 wireless units, but I dont put up with bad sound quality and I like relatively flat response. Not the racks fault, any rack of this type would have been attaching to plastic. external noise but not completely, allowing me to be also aware of my surroundings which is a plus when I cycle.
