In our testing, the Catalyst case lived up to its claims and kept our iPhone safe when we stuck it in a sink full of water, but in our opinion, this isn't a case you're going to want to use on a daily basis.
It's protective, but that comes at the expense of the thin and svelte form of the iPhone. Catalyst's case adds a lot of bulk, plus it makes the volume and the power buttons nearly impossible to use because the material it's made of is so rigid. We also had a harder time using the iPhone's touch screen due to the air gap between the protective cover and the display.
Catalyst's waterproof case may not be ideal for every day use, but it's a great option for situations where water protection is essential. You can use this case to take photos at the beach, in the pool, while snorkeling, and more, and your device will be protected from water, dust, dirt, and other elements.
The iPhone 6 Plus case is available in several different colors from the Catalyst website, and it's priced at $74.99. There's also an iPhone 6 version, which is priced at $69.99, and there are several accessories available for purchase like a floating lanyard, an audio adapter, and replacement parts.
