I bought a black plastic Taktik Extreme 5 directly from Lunatik. It was a nice case, looks awesome, but I didn't really like the way it felt in my hand. Especially for $143 (the cost after taxes and shipping). Decided the same day to return it.
When I installed the case I cleaned everything really well. Within hours I had a really bad rainbow effect on the Gorilla Glass, took up half the screen and was so bad I could see it with the phone on. I have an Otterbox Defender so I'm familiar with the issue and ways to fix it but I did not expect it with the Gorilla Glass. And this was way worse than anything I've seen on my OB. I don't mind popping the case off of my Otterbox once a week or so to clean it but I'm not going to undo and redo 6 screws to clean my case every time I have a rainbow on the screen. Plus, when I did go to clean it the second time I noticed some of the screws had already loosened quite a bit.
Also, that company is a mess. One bumble after another. Their customer service is unresponsive. When I decided to return my case I had to send 3 mails over the course of a week before I got a response. Wouldn't have been a huge deal if they had a 30 day return policy but it's only 10. I didn't want to get stuck with a $143 case I didn't want. Lots of people are having customer service issues with them. I don't mind paying a premium price (which this DEFINITELY is), but I expect PREMIUM SERVICE in return. They make some beautiful products but I will not buy from them until I start seeing happy customers on Facebook and Kickstarter. Hopefully they'll learn before it's too late.
A couple of other things that rubbed me the wrong way. The instructions on how to open the case are INSIDE the sealed case. That's easy enough to figure out but who in their right mind thinks that's a good idea? Plus, backers (which I'm not) are paying $25 more for the case than people who didn't back the product. Kind of sucks for them.
