It probably sticks very well, I had placed it on a Spigen case that didn't have MagSafe, so I could use it on the car mount which is a MagSafe car charger. From 2022 until today (2025) it has never come off and the grip is generally stronger than that of the phone.

The magnet was stronger than the glue and so the product ended up in the trash can. For wireless charging, not even for a joke.

It's fine, but it's better to set it by eye if you don't have the phone that the guide mentions.

Very good product. It does what it says without any problem. I use it with a magsafe wallet and I never had any issues.

Keep in mind, however, that a case with built-in magsafe has a much stronger magnet and makes much better contact with magsafe products.

It also does not affect wireless charging.

I have put it in a case for s23.
** The halolock goes on top of the case, not inside the case because the magnet doesn't hold.

Excellent product and does what it says. I put it in the case and it magnetizes quite strongly to the original Apple magsafe. It sticks so well in the first minute that if you put it on crooked, you can't take it off. After the first 24 hours, when the adhesive is activated properly, it may require some heat to remove. It loses one star because the system that attaches to the port to align it moves easily in USB-C. In Lighting, which I tried, it sits better. This results in needing a little more attention to avoid putting it on crooked.

It sticks very well to magsafe, but if you stick it outside the case and now you want to stick it from the inside of the case, things are difficult... it doesn't hold and falls easily. For anyone who wants to stick it from the outside, it magnetizes very well.

I put it on my iPhone 13 Pro, which is wearing a Spigen case, and the phone stands firmly and very securely on a car mount that charges it wirelessly.

On an iPhone 13 with a Spigen case, it works well. It is equally sturdy as the mobile's magnets, but due to the gap it has from the case, it doesn't click like the magsafe without a case. However, this doesn't hinder its use as it always functions.

Very good grip on the ESR magnetic base, I wonder if it will be as good on other types of magnetic bases. It withstands vibrations, the only thing that moves is the base

It does the job it is intended for. It requires attention when sticking it, as it breaks when you try to remove it. I use it in a case for iPhone XR along with a MagSafe charger/car mount of the same company. Strong grip.
