As described

It's very good because I just took my first exam which is statistics and It's a very challenging course so all I did is put my cell phone inside on the calculator to memorize the formula's to solve the problems. Also, I used pictures that I've taken to help Utilitize what problem's I'm stuck with the most.

I like it guys is very nice

Couldn't be simpler to use just clip it and go

Would recommend this to anyone really useful

This thing is amazing works exactly like I needed

Works as expected really helped me out

Phone fits in perfectly no issues at all

Made a huge difference on test day so glad I found this

Really clever design makes it super easy to use

Cant believe how well this works super happy with it

Works perfectly love it

It's so easy to use just clip it on and you're set

I love this thing so much it’s the best

Totally saved me during a test great idea
