I've been using the Trident Kraken A.M.S. cases for a few years now with my Samsung Galaxy S2, Galaxy S3,ipad 4th Gen, and now for the Note 10.1 (2014). With a toddler at home, I swear by this case. He has whipped my ipad across the room and even dropped it on the concrete. Not even a scratch or dent on the case or tablet. I don't need a physical keyboard and I abuse my phones and tablets, so this case works perfectly for my needs.
There is two things I don't like for my Note 10.1 (2014). First, it sucks major A$$ installing this case. It literally took me an hour trying to get it on. The silicone piece wouldn't work with me. Secondly, the touchscreen isn't as responsive as my previous phone/tablets. You need to press a little harder with this edition.
Overall, I like these cases over the Otterboxes and others.
