Holds the phones well, but the springloaded top holding bracket is REALLY tense, I was almost afraid it was so tight it was going to crush the screen, but I just pulled it open and closed a bunch of times to loosen it up. Somewhat difficult to get in and out of, but overall it holds the phones (iPhone 5S and Samsung Galaxy S4, both with cases) quite well.
good tripod for the price. the product is 100% the same as a product with different picture and price (I ordered both). go for the cheaper.
Galaxy S2 fits only by using force (not recommended) . the upper part will break probably very soon.
