I had to use three of the backs to keep the fake gauge on my ear, they also hurt a lot... Don't bother buying.

Most of the toppers stuck to the paper backing. Not sure if it was a user error though. I'm not very good at getting these off the backing at times.

The back is comprised of 3 pieces (although the product description does not tell you this). 1 piece for the black top, 1 piece for the aluminum middle, and 1 piece for the black bottom. The top piece does not adhere well because the camera lens and flash take up too much space for the product to adhere with integrity. I'm in the process of retuning the product.

Here's what Media Devil Customer Service says:

"I'm sorry to hear that you're experiencing some difficulties with your iPhone 5/5s back protectors. First of all, just to explain this to you, the reason why we have designed our back protector in 3 separate 3 Dual-tone pieces, is that this is the only way to maintain the original look and feel of the iPhone rear, as intended by Apple. Unfortunately it's not possible to design a single back protector that consists of both our Crystal and the Matte Clear material. Additionally the two intersections between the aluminium and glass sections are slightly raised, so a full-size protector would lift along these areas, creating very unsightly long thin bubbles.

Now, you mentioned that the top protector part keeps peeling off your phone, this is typically an indication for a slight misalignment, however if you could provide a photo of the entire back protector on your device, we'd be able to confirm this for you. There are two things you'll need to bear in mind when applying your back protectors: firstly, the iPhone 5/5s rear has a bevelled edge, so if your protector is misaligned and goes over this edge, you'll catch it every time you're taking it out of your pocket/bag/pouch. This will then result in the protector losing its adhesiveness and peeling off over time. Secondly, as mentioned above, both intersections between the aluminium and glass sections aren't level, so if your protector gets in contact with them, it will start to lift and bubble up.

Looking forward to hearing from you! :)

Best regards,

MediaDevil

There is a handle on the back that makes it feel quite awkward.

They came taped together, so the middle area was squeezed together. I don't know how to stretch it back out. Doubt I can. So I only use the 2 ends. But it's saved things from falling down there so I guess they served their purpose.

Not the best but they worked for what I needed them for. Unfortunately the backs started to separate after the third time wearing them. I only really wear them for bumming around so it really isn't a big deal to me. I did not expect too much for the price I paid. They are very cute and look awesome with my sweats and leggings, which is the main reason I purchased them.

these match nicely with our seats but the back components that  are meant to anchor the it to the back of the seat are not only too short but the plastic anchor is too big. we use them but they are loose and move around - makes me nuts but it is better than using a towel.

I was concerned about use on larger cabinet doors. I ended up putting 3 hinges instead of the 2,that I normally use.

I love that I no longer have to prop up the back of the laptop to get the slant I want! However, I did find that the velcro attachment system didn't hold very well. I ended up using some nice, black duct tape to hold it in place

This frame served its purpose. However, the backing on the frame kept shedding on my picture itself no matter how many times I cleaned the glass, when I inserted the picture, there were small black specs on my picture. Therefore, I gave the product three stars.

One of the racks didn't have the two holes needed to bolt the backrest.

I love these seat covers my star rating is more so for the fact that FH doesn't sell the front seat covers in a separated package. I tried to install the back and realized (at my own fault) that all three headrests don't pull up. With that being said I kept the front two seat covers because they really are pretty. Tricky to install but the video guide helped. I do want to let people know that if you do have the luxury of having a three heat rest removal in the back there is directions to install, those directions suggest tearing the seats out. Since mine don't work I cant help with that but wanted to mention it. Amazon was kind enough to refund me $20 bucks out of the 50 I spent because I cant use the back covers. I'm looking for another option in the back but sadly may need to ninx the print which is bit of a let down.

Back film is 3 separate pieces and easily comes off. The front film is fine though.

I like these but it is 3 pieces so you have to take extra care to align straight. I guess maybe it has to be 3 separate pieces or you would notice a "clear" backing? so maybe they should include a template for mounting help. They look good though and seem well made.

Happy with the product however had an issue but they took care of me. The back pieces didn't stay on with the adhesive but they refunded me for the backs. I keep the fronts and I'm happy with them. You really have to prep the back area and clean it good for them to stick .

covers back of 3rd row seat, and folds down with 3rd row back, to provide full protection when 3rd row is not in use.

These 3 pieces kept me from purchasing a new mount and the process of rerunning new wire in my pickup
