I registered for an account here simply to be able to add my two cents regarding this case. I read all I could about the Glide Caseless, and really was looking forward to getting a very thin bumper case to show off my white 4s. It took about 3 weeks to arrive, which I expected from the website's warnings, but which seemed a bit long to wait.
Once it arrived, I followed the instructions to a T and found that the case did not snap perfectly together as it should have. I tried removing it (carefully, because the aluminum is slightly malleable) and re-installing many times, but could never get a perfect fit. I really liked how lightweight it was, and the look, but was worried that it wouldn't hold up, since it didn't seem to fit perfectly.
Less than 2 weeks into ownership, I dropped my phone from a height of about 12 inches. Here is the description I sent to Caseless of what happened, with my refund request:
"I would really like to return this case. It does not fit properly, and is not, in my opinion, worth the price, because of that. I dropped it once, today, from less than 12 inches (I was sitting on the ground) and the case now gaps and fits even less properly than before. Please advise on how to return. Although I understand that your policy indicates that you cannot replace or refund damaged or dropped cases, I believe that an exception should be made. This case did not even last 2 weeks and does not protect my phone. Thank you."
Guess what? I never got a response. I followed the protocol of requesting a refund through Google Checkout, but nothing. I spent $59.82 on this piece of crap, including shipping, and I finally gave up after 2 months of owning it. It would barely stay together after that length of time. I gave up and went back to an Incipio case, which was $15, and which I expect to last MUCH longer.
Please think twice before you order this case. Unless you never put the phone in your pocket or bag, this case will not last.

I only wish the company had responded to my emails. I am out $60 for a few flimsy pieces of aluminum. So disappointing.
