It's a nice product but just keep in mind That it will not last for more facts a year, so buy 2-3 to have enough replacements.
For a comparison the official bumper from Apple (for my iPhone 4) did not last more than a year too. So there are not quality issues, it's simply the fact rubber / plastic will stretch after some time or degrade after intense use.
An advice DO NOT remove it or change bumpers (with different colors) you want to make it loose / stretched a lot faster and leave it until it place it breaks. This way it may last 2 years.
