My two-year-old son has an iPad mini. We put it in the OtterBox defender series case. It has withstood a full year of everyday use. It has been dropped countless times, It has unfortunately been the victim of a few temper tantrums (ie. I think my two-year-old has a future in the discus track and field event) And remains fully functional with no damage.
My wife and I also use the OtterBox defender series for our iPads and have found then to be extremely durable.
Before arriving at the OtterBox defender series I fully tested the
Griffin Military Duty Case: The current version of this case is a lower quality than the original series for dust sand and water.
Life Proof Case, The marketing for this case was great but this case has many many drawbacks. Starting with the additional audio connector you need to carry around with the case if you desire to use headphones. The cover (an additional $40) and stand are flimsy and low-quality material. Additionally, there is no where to store the cover while it is not being used. The unit is fully protected from sand, water and dust This level of protection has drawbacks. The speakers are muffled for a low quality audio experience, and the microphone will not pick up your voice for dictation. Lastly, when you attempt to return your case to Life Proof they require it to be in the original packaging along with a 15% restock fee.
The OtterBox defender series comes with a durable and easy to use cover with stand. When not in use, the cover attaches to the back of the case for extra protection. The case is very durable and has grips on both sides for easy handling. Additionally, the case has a screen protector and all features of the iPad are fully protected, but easily accessible. I highly recommend this case, Because the cost truly meets the value of case.
