    • Good case
Color: Bespoke Way (Blue)
I've always liked otterbox. They are a little more pricey than others but they understand the need. The case fits great. Looks good and works well. I like the waterproof usb cover. I do a lot of different things in my wood shop and I'm always getting sawdust in my ports and microphone. This seems to help with that a lot. It feels nice in my hand and it's easy to hold onto. ... show more

    • Great case!
Color: Bespoke Way (Blue)
Perfect for with a front screen protector on but it didn't fit with the rear camera protector on. The rim around the cameras is pretty deep so it feels ok to not have the protector on them, and the pictures are much better without the protector on.

    • Improved material
Color: Bespoke Way (Blue)
After many years, my rubberized Otter ox wore down & then started falling apart. I don't think I'll be replacing my phone soon, so I bought this Otter box to replace the old one. This harder case slips on more easily, has a smaller profile, and seems more durable. I like the feel better, too. It's more like holding a solid plastic case than a dry wet suit. The plastic-like material is much stiffer than the rubbery old case, which isn't a problem, except the small cover for the charging point is quite stiff. It's the first think that fell off my old case. So I'll take stiff over easily worn, if that proves to be the case. ... show more

    • Great case for protection...However..
Color: Black
You really can't complain much about this case..It's simple and most importantly, protective. However, if you enjoy using cpu intensive apps or 4k video recording, the case seemingly traps the heat. If my Galaxy 21 Ultra is on medium to high processor use, within a few minutes, the phone begins to grind down and the camera app shutdowns. Remove the case, works fine. Not an anomaly either as the same exact things happens with my coworkers. I believe the rubber insert to the case is trapping alot of heat that can't disperse & disapate properly. Overall, great case and does what I need it to do as I rarely game or take videos. ... show more
