Other colleagues agree on the Keen sole; they get a C- in slip resistance. Dolby headphone is a waste of time (unless you like the echoey ambience of a sewer tunnel in your games) and annoyingly turns itself back on every time the mixamp is powered on. ***Update:Anker sent me a new pair of headphones with instructions on how to reset them. I wear them every day around the house & garden & out & about. I have nothing bad to say about this rack Im so glad I did my research and bought this one. They did fit slightly large but for a toddler he is just fine. 5 jack cable is long and well structured and can be hung well. Further research showed only issue is they sit straight from the hitch so a hitch low to the ground would cause issues, rest was great reviews. My only concern is that they can go on and off pretty easy but it looks like they may fall off and could get lost easy. We did anchor with dry wall bolts and they are solid.
