These wireless earbuds were a very pleasant surprise. The "locks" that holds down the plastic cover are difficult to get in, Until I figured out you had to snap down the cover first. Since they are a cheap price-not worth returning because I have to pay for UPS to pick up. The great thing is they are super easy to use. This is exactly what I was hoping it would be. I have just put it together this afternoon, so if I experience any problems I will come back and edit my review. The only complaint I have is that all day comfort sole wears differently than the wobbleboard- but this shoe only comes with the all day comfort sole. Especially for the price (I got an even better deal thru an offer from the Cheapskate), these are working out great for me and I wouldn?t hesitate to recommend them. A heavy bike may be difficult to lift up, so you can lower the rack to the ground, install the bike, then lift the rack to the horizontal position. However, the build quality, appearance and fit and finish and surpassed my expectations at the $39 price point.
