I’ve had one for a little over a year & it’s still in mint condition. This if for 13 mini. Got it on ebay for about $20.

Yes. 2 months with silicone case. 0 problems. If you don’t stick it in your ass like others do it will be ok

Gets greasy easily, i would go clear or leather depending on the model you have

It’s good if you buy it from AliExpress for 2 bucks, I have multiple and they are holding on pretty good.
