Perfect, I use it at the office to support my phone while using it on the internet and it has been incredibly helpful. I recommend this version that has the ability to elevate the base, because the extra height helps for better screen viewing of the phone and anyone who wants can also leave it on the lower level.
I was looking at other stands with good reviews, fearing that maybe the height or the tilt would not be enough, but I chose this one because its construction seemed more sturdy, as it turned out to be. It's perfect for on top of the desk or on a table. There is no chance for the phone to fall or not be securely held on the top level. It is very stable and I believe it can comfortably support a tablet as well, as I have seen in videos on YouTube.
One of the very positive aspects is that it can be folded with 2 movements and it doesn't need to be constantly unfolded on the desk.

It does what it promises. It has ugreen quality and it's better than the one I bought that is not adjustable. Practical, cheap product. Nothing complicated. It's worth it.

Very good. It does what it's supposed to do. I have been using it for a long time and I have nothing negative to say. And the price I consider to be very good (~6.5€)
