I ordered an Otterbox Defender from Amazon which was delivered today along with a tempered class screen protector. That was my only Otterbox option if I wanted a belt clip which I currently use for my iPhone 6. It's a little bulky compared with some other cases but I chose it for the extra protection it provides and I already have some experience with an Otterbox that I have on my iPhpne 6. Screen protectors were pretty cheap on Amazon. Only paid $7.95 for a 2 pack. It got good reviews so I took a chance given how inexpensive it was. Otterbox sells an Alpha Glass Series screen protector which sells for $20.38 on Amazon. Can't figure out why it's so expensive. It may be because it's guaranteed to work with the case I bought. Prices for these tempered glass screen protectors are all over the place on Amazon.
I bought a Case-mate Naked Tough, because they are minimal, and have protected my 6s Plus for 2 years through many drops. I didn't buy a screen protector. With my 6s Plus I never used one (for the first time), but I keep my phone in a microfiber sun-glass bag.
Should I buy a screen protector for X?
