This is exactly the stand bracket I needed. I use it for my iPhone XS Max. I'm not sure if a tablet can be used for this, but it doesn't look like it. This stand holder is stable with little movement and holds my iPhone XS Max firmly. I bought another one from another ebay seller and it kept falling and broke after 2 weeks. Definitely worth the money.
