"The Catalyst Case has amazing features such as anti-slip textured grip and if you do somehow manage to drop it, it doesn't matter because it has higher drop protection to 10ft."

" Love the turning dial for the silent mode covers it to protect it and functional. No scratches and very durable. Awesome no second thoughts buying again for all my future iPhones. Better than OTTERBOX! "

" Love this case! It is slim yet sturdy, I have already dropped a couple of times, once on cement and then on tile surface. I especially like that it has the openings for the cord strap. "

" Awesome case. Only iPhone case I’ve ever had that doesn’t lose it’s shape/form Or lose it’s sturdiness. Never had any issues protecting my iPhone. Love the mute switch and the buttons as well. "

" I have had this clear Catalyst case for a month and have really enjoyed it. My favorite feature is the wrist strap that comes with it. The case is protective and I like the rotary vibration switch. The clear back makes my phone stand out. "

" I have 3 boys and the case I got needed to be the best. Needless to say I have dropped my phone multiple times now over the past 6 months I have had this case and it’s held up great. Not a scratch on my phone! "
