This is the awful way I shop. When looking for a slimmer and trimmer iPhone case, I looked at every alternative. This is what I found:
$25. This is the case my wife uses. Fantastic trimness and grippiness.
$9. Nice price.
$10. Interesting look.
$20. The uncase.
Slice 3 for 4S (thinnest case at 0.35mm thin)
$26. So thin. Is it grippy enough?
Zero 5 PRO Clear Collection UltraThin case (0.5mm rubber and plastic case)
$20. Thin with a rubbery side. Looks great.
Grey AeroGrip Edge (bumper)
$15. The bumper’s dimensions are greater than some cases.
Skinit Infinity Case (custom images on back)
$25. Made for use with custom images.
Hex X Supra Core (black or white fabric case)
$16. Great look and feel to these sturdy and grippy fabric cases.
$35. Futuristic. Complaints that the buttons are too hard to press.
$15. A simple and thin bumper. Grippiness may be an issue.
$20. Another un-case. If you never drop your phone, you do not need a case.
$10 Grippy edge and it comes in white.
$4 Completely cheap feel. Too Slippery.
I chose the terrible $4 no name bumper from Ebay. At $4, it is probably overpriced. The case was far to slippery for ordinary use. After a little internet research, I found a tip to help make it grippier. Rub it with a scouring pad. After about a half an hour, the glossy plastic became a bit duller and much grippier. The case also took on a green tint from the scouring pad. You know the old saying. You get what you pay for.
