My Dual Pro case developed a crack in it, on the hard case, from the power button towards the LED hole.
I've had it three months, and I haven't dropped it and I do not put it in my back pocket, so not sure how this happened.
While there is undoubtedly variability in experience and quality, my Dual Pro is going strong; probably had it on for the better part on 10 months. It's taken a beating over that time -- numerous drops, including on hard floors and pavement -- and never so much as a scratch to the DTEK60 inside or failure of the case itself.
Things I like about it from a long term experience perspective:
- feel continues to be great in the hand; nice soft matte finish that doesn't get sticky
- the dual layers allow a metal plate to be inserted in between for magnetic mounting, e.g. in the car (see scosche products)
- at first I kind of hated how much it came up around the screen, but in the long run I really appreciate the confidence that has given with drops and placing it upside down; screen looks as good as day one.
Dual Pro by Incipio is the way to go! I have had it since December of 2016 and still protecting my DTEK 60 like a champ. Got it for $15 usd as well back then. Super happy with it. Wash it and clean it when necessary. I highly recommend it.
