Rated 5 out of 5 by from Phone cover It fits my phone. Just wish it came with something to protect the front from anything, as the case only covers the back and sides with no protection for the screen/glass at all.

Rated 5 out of 5 by from Great! I have used defender since s5. Phone has been dropped several times and is always unharmed. My only issue is that it is a little bulky.

Rated 5 out of 5 by from Otter box is the best product on the market I ordered mine as soon as I got my new phone but unfortunately the phone company I ordered did not come through with my phone but I know anybody who orders an OtterBox is going to be extremely happy with it every phone I have had is covered with an OtterBox

Rated 5 out of 5 by from Otterbox User Forever Since the first phone I placed in an otterbox, years ago, I've been hooked. Every new phone I get I have to have an otterbox or I feel my phone isn't fully protected. I also get them for my children's phones. The otterbox is always worth purchasing because it protects the phone so well.

Rated 5 out of 5 by from Best Protection Nice look and perfect fit but I would like to see a tempered screen protector for the infinity screen that does not pop off with the case for my Galaxy s21 plus 5g

Rated 5 out of 5 by from Best Case on the Market I have always liked Otterbox, but they are a little pricey. I would like them to bring back the built in screen protector and also be compatible with fingerprint recognition.

Rated 5 out of 5 by from The best! I have been using Otterbox Defender cases on every phone I've ever owned going back twenty years. I have never broke a phone using a defender case. If anything ever goes wrong Otterbox stands behind their cases with a full lifetime warranty. I always recommend Otterbox to everyone trying to protect their electronics.

Rated 5 out of 5 by from Great case I had this exact case on my previous phone for years. I liked it so much that I didn't carry the new phone until I had one. I pair it with a tempered glass screen cover for complete protection. Worth every penny.

Rated 5 out of 5 by from The preferred case I bought this about a month ago and as always, it's worth the money. Only issue is the outside cover doesn't stay connected in the top right corner because of the camera location, there's not enough material there to hold it tight.
