I'll give it to you. One phone every 2 years (personally I try to hit 3 but batteries don't always cooperate) and I typically spend $7-9 on a TPU case and $3-5 on screen protectors. So on average, $12 times five phones in a decade is $60. I (don't) really feel like I wasted my money. Grip alone makes the case worth it to me!
