I never even heard of them before but they use D30 like Tech 21. Looks like a decent case but Mobilereviewseh did a review on the iPhone 7 one and the screen totally shattered on a 6 foot drop on a flat surface.
I remember my S2 I had the early version case that was 3DO exclusively sold by Tmobile and looked similar and I dropped it out of my car about 2 feet onto pavement getting out and nothing happened to the phone.
For the price tag this goes for I'd stick with the Otterbox Defender or one of the imitation Defenders you can buy.
