    • Extremely durable
Color: Black Size: Samsung Galaxy S21 Ultra ONLY
I have used other cases on my phone before, but Otter Box is the only one that actually protects my phone. I work a very active strenuous job where dropping my phone on dangerous surfaces is not uncommon. I've had the same Otter Box case on my phone for about 4-5yrs and it has never failed me. I'm replacing it now due to enough wear and tear on the outer shell, but it's still worth it. Best case you will ever find to protect your phone. Sure maybe you can find more variety in colors on other brands, but this one is far more durable and black is classic. ... show more

OtterBox is top-notch phone protection for sure.. If you want your phone to last for a long time then get OtterBox.. My last OtterBox shown in the pictures lasted me for almost 4 years and man did I drop my phone a lot.. never once did my phone ever break.. Durability is definitely a strong point with the OtterBox. Personally I like the look of the OtterBox and the feel that it gives to the phone it does not add too much bulkiness and the texture and feel are right for my hands. OtterBox is really the only brand that can last this long. I have definitely tried many other brands. ... show more

    • tough, durable, functional
Color: Black Size: Samsung Galaxy S21 Ultra ONLY
These are great. I get an OtterBox of this type for every phone. They are very durable, look nice, and have a belt/pocket clip. It will protect your phone and will last until use and your skin oils loosen up the rubber. I get at least a year out of a case if not a year and a half. I usually have 2 cases per phone. There is a little piece that covers the charger. I always cut that flap off with scissors. The very first case of this type I had, pulling it up to charge it caused this warping/buckling thing along the bottom. If you cut the flap off, it eliminates the cause of the issue. From the second case on, I always cut that flap off. These may cost more than other case options but the quality is well worth it. It keeps your phone well protected. ... show more

    • Solid protection for your phone.
Color: Black Size: Samsung Galaxy S21 Ultra ONLY
Fits snugly around your phone, no tools required. My phone is old,but I drop it with regularity. My old case did its job, but shattered at the end. I knew I had to get another case. The clip to hold the phone to your belt is a little suspect or I have not mastered its use.
