Pros:The product was great for the price. It has a nice tight fit.Cons: Item was subject to false advertising. The 3 interchangeable ear hooks as described under Technical Details are not included with this product. I was also displeased to read a simple reply from the seller saying that it just doesn't come with it. IF it doesn't come with it then don't advertise it.Buttons rattle a bit with fast movement but under normal use they don't.
