I previously had the corresponding Spigen case, which, however, without hitting somewhere, started to make "wounds" that bothered when I touched the phone to my face. The ESR has a more matte texture, so it doesn't slip from the hand. It does not add bulk and protects the phone. There are some slight gaps on the buttons to make handling easier, which may collect dust, but you can simply remove and clean the phone from time to time. Wireless charging works perfectly and holds the device securely
