image not available This Catalyst phone case is the BEST! My phone took beautiful photos through the case - both underwater and above water - the case kept my phone bone dry.
image not available I can wash off my phone a bunch of times a day and not worry about if it’s alcohol sanitizer, germicidal wipes, or surgical scrub soap.
image not available Case is very well made and seals perfect. I can even use it on my gimbal. The Lidar works great too. Had a drop onto hard tiles. Not even a mark. Works in the pool too. Worth every penny. 👍
image not available I have 3 boys and the case I got needed to be the best. I have dropped my phone multiple times over the past 6 months I have had this case and it’s held up great. Not a scratch on my phone!
image not available This is the best case I have ever had; it is worth the purchase if you want to keep your phone away from water.
