I do not use the Smart Turtle for my smartphone or tablet, but for my Macbook.
I was looking for a small inconspicuous laptop stand and just happened in a YouTube video ([...]) met with the Smart Turtle.
You can see it at all under the laptop and it can be super push handle without slipping there.
The quality seems at least for the first impression really very good. If I should make other experiences later, I will revise this review.
Am now I am completely satisfied anyway, so it was great!
