I purchased this specifically to hold a Ipad 2 (9.5") in portrait position. It does not. It doesn't even hold an Ipad mini (8") in portrait position very well. It will hold it if the Ipad is almost perfectly upright but it will topple over if you adjust the angle to be anything other than upright. If you need it only for landscape position, it is a good buy. Folds fairly flat and appears to be durable.
I've bought five different cell phone stands in the past couple of years and this is my favorite by far. Firstly, it actually holds my phone, a Pixel 2XL with a credit card holder case, when others are designed only for slim phones or narrow cases. Secondly, it holds the phone a perfect height off of the surface to allow you to plug it in. Finally, the angle of the phone adjusts and the whole thing folds. This lets you redirect glare and makes for easy packing & travel. Highly recommended - I've since bought multiple for bedside and both work and home desks.
