As stated in the product description, the waterproof case works great. I was able to unlock my phone and use it regularly. It recognized everything on the touchscreen and had no lags or crashes. Even still photography worked great whether you're doing it with the front or rear camera. I mostly use it when I go to the beach so it keeps the sand out well but then you have to scrub the outside really well before taking the phone out of the case so the sand doesn't get into the case. I haven't taken it underwater but I think there shouldn't be any problems. One downside to the waterproof case is that it's a bit awkward to put on and take off. I have an iPhone 7 plus, it fits very tight. Pressing the power button on the side is also a little tricky as the plastic rim covers the power button. It also won't fit your phone if it has a case. I would understand if I had a thick case to protect my phone, but I have a basic thin case that probably won't protect my phone if I drop it. Apart from these shortcomings, the case is great, especially when you're on vacation.
