Really good sound quality. These also come in different widths. I had circles hooks that came with my rack. Still deader than disco. What I don?t like about them is they wobble loose during exercise and when I try to reposition them they pause and/or turn off and completely disconnect. Why was I sent wrong UK size ? I have bought UK 9/9,5 but got one size down ! In addition, I received a little surprise and a personalized note. I am very picky on my seasonings, I like organic and certain brands and this spice rack was perfect for my needs. It sounds great but it doesnt last too long. If you have a smaller head, the cat ears look a little silly.
