talking about defender right? yes... quite bulky. however, once you've had it on, you'll get used to it and most likely like it (since your already considering you must like the look). The otterbox comes with a built in screenshield. However, there is a watermark effect which can easily be fixed with baby powder or a screenshield on the phone. (watermark depends on the case, i think newer cases not as bad but as the screen gets a little bit loser watermark gets worse... i think anyway)
all in all, i think you shud go for it. i always thought it was too bulky of a case, but after buying two fakes one for my girl (she liked it too) i ended up buying a real one. ANOTHEr great thing about otterbox... I sent them an email telling them I get the watermark effect (i bought this one off ebay for like 20 bucks), they sent me a brand new one... basically got 2 otterboxes for 20 bucks lol so go fish around ebay for a good deal.
