We bring our smartphones with us everywhere these days, even places that we probably shouldn’t, like poolside or the beach. It’s for these latter places that something like the Keynice Universal Waterproof Case for Smartphones comes in so handy.

The packaging for the Keynice Universal Waterproof Case for Smartphones.

The contents of the package.

Available in three different colors – blue (reviewed), pink, and black – this waterproof plastic case protects your smartphone against the elements, including water. IPX8 certified for a waterproof depth of 67 feet (about 20 meters), more practically, the Keynice is designed for repeated water insertions of up to eight feet (about 2.4 meters) for 30 minutes.

One pair of snaps, with the other pair attached to the bag.

My Apple iPhone 6 Plus in Rokform case inserted in the sealed bag.

In addition to its two optional straps – a neck strap and an arm band – the Keynice has a simple five piece design. One piece is the plastic bag where you insert the phone, and the other pieces are two pairs of removable plastic snaps. You remove the two pairs of plastic snaps, insert the phone in the bag, then reassemble the two pairs of plastic snaps until you have a seal.

Running water over my phone.

While the Keynice is designed for smartphones up to 6 inches diagonal, it did struggle a bit with my Apple iPhone 6 Plus in its Rokform case. It fit, but was not easy to insert and remove. Smaller phones, or larger phones without bulky cases, should fit much better.

The neck strap attached.

In my testing, where I ran it under the sink and submerged it in a pot of water, there were zero leaks. Whether my smartphone, my wallet, or anything else that might fit in the bag, I’d feel confident it would be protected. In addition to being able to manipulate most of your smartphone’s functions when it’s inside the bag, the clear panels allow you to easily see the screen or whatever else happens to be inside.

The arm band attached.

Thanks to Keynice for the review unit.
