“This case really is one of the toughest you’ll find. It’s lined with an innovative material called D30 that actually becomes stronger the harder it’s hit.”

Gear4 D3O Samsung Galaxy S7 Book Case is rated 4.0 out of 5 by 5.
Rated 5 out of 5 by from Highly recomended Had this for over 1.5 years and have dropped my phone several times including on pavement. If it wasn't for this case my phone would easily be history. It also provides an extra level of grip when using phone in the hand. Starting to look a little bit jaded around the edges but still going strong.

Rated 5 out of 5 by from So robust I have had this for two years and after extensive travels and many drops it is starting to look battered but the phone is still in mint condition. It’s been a phone saver time and time again. It’s only downside is it doesn’t prop up terribly well but it’s almost bomb proof. Would I recommend it? Yes, every day of 5he week and twice on Sundays. Such an expensive purchase needs the right level of protection, this is it.

Rated 5 out of 5 by from All round great phone cover Purchased this product over 12 months ago. I was slightly reluctant to purchase the gear 4 due to the price but am glad I did. I've dropped my S7 edge countless times and when its removed from the case its like brand new. 5* rating for me
