Changing iphone cover every year

[battledome64]

Do you have the habit of changing iPhone cover?

After 1 year the plastic turns yellow
Some cases start to fall apart

Noticed that not many retailers selling older iPhone model covers. Some charge especially high for branded older models cover

I just buy $3 tpu cover change once every 3 months.

$4 Ugreen temper glass change once every 3 months too
