At some point (but no later than when using a docking station, a car mount or performing a soft reset) you will not get around it, remove the cover ... and that is the problem here. Each time removing the Case-Mate the rubberized surface of the HD2 is slightly scraped by the sharp edges of the envelope. After only three times removing the shell it was with me already the case that at a tiny point already was seen the bare metal of the phone. This problem has now been reported by several buyers (also in various forums) and at this point you should worry whether there is a protective sheath is damaged really makes sense that a cell phone STRAIGHT THROUGH.
My Conclusion:
No recommendation to buy, because who needs to remove the Case-Mate more than 1-2 times again will have no long from his new cell phone ...
