This came in today and it was very easy to put on the switch. It does have bubbles but they will disappear after a little while. I just got this switch used the other day and it did not have a screen protector. The screen had a few minor scratches, but the screen protector makes those scratches seem like they never even existed. The reactivity on the screen is very good. It is practically the same as it would be without the screen protector.

Super easy install!

Size: 7.9"

Super easy to install, you really can’t mess it up since the guide is so helpful! Plus you get extra shields just in case! I’ve had mines for months and it hasn’t cracked so the durability is great! Scratch free and smudge free!

The ultimate water bottle

Color: Iced Breeze, Size: 24 Ounces

I can’t believe I’m so excited about a water bottle. The design is amazing - I love that there’s no straw poking up but there’s still a straw sip function. I like that the carrying hook doubles as a lid locking mechanism. This bottle feels very sturdy but it’s sleek and easy to grab - I have small hands and it isn’t a problem for me to drink from with one hand. It’s also really nice that this bottle fits in standard couple holders both at the gym in the machines and in my car. The color selection is so fun and I am pleased that my bottle looks exactly as pictured. My water has stayed cold and my ice cubes frozen for over 12 hours now. Cannot recommend enough!
