The magnets are quite strong but don't seem to interfere with anything else electronic (I have used the magnets to attach to the top of my old PC case while I was watching repair videos, as well as microwaves and fridges so your mileage may vary).

The stand works pretty well, but it doesn't always want to be put flat again afterwards leaving me fighting it for a few seconds after using the stand. I it also feels pretty cheap and flimsy but has held up pretty well to the abuse of daily ware. It would be great if they included a QR code linking to suggested placements for various models of phone that had wireless charging but not internal magnets. I recall the video showing that you could put a finger between the plastic bits in the middle as an option to hold it, as opposed to putting the plastic between your fingers and that is a bit more comfortable in my experience. For the price I would expect the material to be a bit more scratch resistant and the closure to be more consistent but it is a pretty good product overall so far.

TLDR: Sturdier than it feels in the hand, and strong magnets. If it actually closed without me having to fight it most times I use the stand I would give it a five star rating
