The first support I received support was great, but It was not high enough to hold my Samsung Galaxy Aplpha with a cover on it. I have a Spigen ultra hybrid transparent back cover, Relatively thin Compared to others, but the support's height extended to the maximum what not Sufficient to hold it. I managed to squeeze the phone with cover in, and the extension joint was close to breaking point.
Very shortly after this experience I was contacted by the seller and the slightly larger Offered version of the holder. This is just a little larger, enough for my phone with its cover to fit, and likely for some larger phones.
