Hello dear Robert,
Thank you for your review. If the MagSafe stand ALFONS is too unstable for you, we recommend installing the supplied 'Suction Cup' suction cup foil. To do this, simply remove the glued-in rubber on the underside and replace it with the sticker supplied.
The film does not contain any adhesive, but consists of millions of microscopic suction cups that stick to any surface with light pressure. You can find more information on the product page. This makes your stand really secure and firm.
If it works well, you can give us 5 stars :-)
Best regards from Hamburg,
your GOOD WILHELM Team
