I am looking into TPU cases....and could use some help. Basically...I have a Case Logic side holster that I will wear in some instances where I don't carry my phone in my pocket. So I am looking for a slimmer case that could cover the phone...yet still slide into that side horizontal holster. So I am considering a TPU case. Also would be great if it is 'clear' so the Apple logo can be shown for a little style. One thing I noticed with a TPU is that if it is clear....it bubbles up on the back of the phone. Like a bad screen protector install. Noticed also that some TPU cases aren't so great with screen protectors...where it cause it to bubble up. Does anyone have any thoughts about TPU cases???
