I like the screws they seem really strong. The other is better on the angle but is elevated and therefore top-heavy when holding the phone. I have knee and hip pain making it difficult to walk, but these sandals make my life so much easier. no weird squeaky sounds from the soles while walking around at home on wood floors and tiles. reached out to Samsung and they advised serial does not exist - most likely fake item and will not be covered under any warranty. If the key insert could be located on the side of the barrel, rather than the end, it would be perfect. These have been great and I could still wear them and see how long it would take to wear through the cloth liner I suppose since they still fit and feel fine. SPEAKERPHONE: I didnt test this extensively, when I made a call with it everything went fine - not a great tool for speaker phone use but not worse than most bluetooth speakers. Logitech wird immer schlechter. I dont review very often but felt compelled to write this review.
