Installation wasnt too bad. also they seem to be very cheaply made. It is so cute, I love the gold color strip on top of the shoes. Like clockwork, 90 days since I bought the product the right ear stopped working pretty much mid song. I toss one in every backpack I have and they are great for setup of portable sound equipment, charging kits, turning one smart outlet into 3. I was looking for a nice pair of memory foam ear tips, since the ones that came with the AirPods Pro are terrible - turns out these are just about worse. The sole of the shoe fell apart the third time I wore them. Perfect for work as I am on my feet all day I live in chronic pain, I have RA, bone spurs, fibro, flat feet, - I hurt all day every day. I previously had a similar Thule 4 bike car carrier that was great.
