I had no problem connecting this to the IPhone X. I also bought this to test some of my old coins but I had a blast putting all sorts of objects under this microscope including jewelry, insects and random items around the house. I had no trouble connecting this to my phone and the images are very clear. One of the reasons I got this is the adjustable height, scale, and brightness. I didn't see this on many other models and ended up returning another model because it was difficult to set the height and focus sharply.
