Streches like 15 feet then becomes difficult to stretch like a powerful rubber band beyond that.  I bought base on my needs and counted on accurate description. It is not. Even 10 feet you realize it's 'streching'.

Fits fine but after just a 6 weeks of use it is stretching and deforming a very little bit -- about as much as my old one did after  about a year.  So this bodes ill.  But for now it is okay.

Update:  In two more months it became stretched and loose and annoying so I replaced it with a good Moshi brand cover  which has now lasted three times as long and still fits fine.  It costs less than 3 times as much so it is clearly the better value.

Had this for a year and after that time the cover felt "loose," like the hinge area was getting stretched out.

Ring is a little snug but fits well. I imagine it will stretch over time being a rubber ring.

Nice colors and it does the job (I've dropped my phone at least 3 times). The rubber of the case is starting to stretch. I've had this case for about 5 months and it seems like I'll have to replace it after a year.

Fit perfect at first, but after some time seems like the hard plastic doesn't stay snugged to the rubber part underneath. So, I have to adjust it a few times while using or charging.

Rubber gets a little stretchy but not as bad as some cases I have had.  It's a durable case that I would recommend to anyone of my friends

The elastic needs to be heavier duty so it does not stretch so much. After just a few months, I can see the belt is starting to stretch already. My son wears the belt approx. three times a week.

Has worked great for 3 months starting to see the rubber part come off more than normal after some extended wear and tear.

This case is inexpensive and starts off great with a nice look and tight fit....however, over time, unfortunately the rubber stretches (especially if you need to take the phone out of the case from time to time...a reasonable thing to expect to be able to do without ruining the case). Under very normal usage, the case now is very loose around my phone and is annoying. I wouldn't recommend this case, especially with all the other options out there.

It fits a bit snug at first every time I put it on but relaxes after I have it on for a while

It is comfortable for a couple of hours and then the pads move around and have to be adjusted.  It gets a little bit uncomfortable after a few hours

As you keep wearing it it stretches and it starts to feel uncomfortable after a while but you get what you pay for

It didn't fit perfectly but it was ok.  Then within a few days the black on the rubber wore off now it looks ugly.

After the 1st use the rubber starting coming off one of the wheels. I have to pop it back in every time I use it. But it serves it's purpose.

Great product EXCEPT for the rubber outer lining wearing out so quickly. Since its bulky, you would think it lasted longer.
