Finally joined the club!

I've been a Kindle user for ~10 years and I've finally decided to do the switch over to Kobo today! I've been eyeing the Kobo Libra 2 or Kobo Libra Color for a year but couldn't bring myself to buy it yet. I saw someone post a used (like new) Kobo Libra 2 for about $154 and decided to try it out!

So far, I'm loving the physical buttons and how it's customizable. Wondering if I need to put in a screen protector or will the buttons break over time?
