It's like a cross between rubber and plastic

Really cute! It's like a cross between rubber and plastic. It's probably not going to protect as well as a hard plastic otterbox but it will do better than a silicone case.

I would have thought this was hard plastic, but it is actually a little more flexible. Visually there is no difference and maybe thats all that matters, but it feels a little cheap - and thats why I got dinged a star.

It is (as others have mentioned) a plastic case coated with rubberized material.

The front and back snap together once placed over the phone and fit it like a second skin that protects the surfaces of the phone from being chipped or scratched.

The cover surface isn't as rubbery as all-rubber cases so it provides the right surface for me for better holding my phone.

It doesn't look like much in the package, but it works very well.

(I haven't tried to take it off or use it more than once, so I'm not sure how well it would do if you use cases interchangeably.)

I used to have a different platypus watter bottle similar to this with much softer, malleable, better plastic than this.  While this does the job, its basically two sheets of stiff plastic melted together.  It does the job, but I was disappointed that Platypus didn't continue using the same plastic it had been.

I like that you can secure it anywhere, but do not like that it is plastic .  I'm afraid that if some one wanted it they could break the plastic easily.

It is plastic.  That was not what I was expecting, from the photo, or description.

the aluminum is very cheap, after some drops it looks totally weird and deformed. However, the plastic part is good.

It has the crisscross appearance of the similar looking Verizon belt clip case but unlike the Verizon one that has a non-slip rubbery feel this one is a slippery plastic. After having a cell phone for many years without ever breaking the screen- this one slipped through my hands and fell to the sidewalk cracking the screen. Also the on /off switch was very hard to reach through the plastic's opening.

It's okay .. You just have to make sure you don't bend it, otherwise it's hard to put it back on the regular shape, bc it's plastic.

Case is OK. The black portion is harder than I imagined.  It seems more like a plastic than a kind of rubber.  Also, the cutout for the charger is sized such that only the stock micro USB connector fits in.  If you have other connectors which don't fit, then you either need to cut/file away from the connector or cut/file away on the case opening.

It looks a lot more durable than what it actually is.....just hard plastic with a thin piece of rubber. I don't feel like it's very protective.

This is plastic.  My old Incase was rubber.  I could not find another one anywhere.

The way this material lays is very different; sort of like a cross between rubber sheets and cotton sheets.  However, it is very soft and smooth.  I have the ash gray and it looks nice; definitely darker than expected, but that could be due to the lighting in my bedroom.

So what I got was made out of rubber. No where did it say rubber I figured plastic or resin. The quality is ok not great.

I thought the case would be harder, but it is actually like a rubber material, which is okay.

It feels like plastic metal like out of the gum ball machine, it is a very pretty super cheap, too big ring.

I would be happier if it was stainless steel on the inside as well, instead it is some rubbery-plastic material.
