TPU cases have a really good grip. It holds firm on the dashboard of your
car, and will never slip out of your pocket (well, rarely!). If you want a case
with excellent anti-slip properties this is your best bet.

complaints often heard about silicone is that the sides can get a little floppy.
It's less of a problem with phones but on larger devices like extended batteries
the problem is really magnified.
TPU cases have a rigid structure so they have the dual benefits of being soft
like silicone but being very firm almost like a hard plastic case in some ways.
