Good day. I have a giant skull with a circumference of 60.5cm. Can I still use the Hövding Airbag 3?

Please be careful using this product. This was brought up in a Swedish documentary that investigated problems with these airbags. Here is a segment translated: Helmets with a known fault are sent to customers Hövding's management has always told the media and customers that it is a problem with the software, that is, the program that controls the helmet. "We made an update in July so those sold today do not have the same problem," said Hövding CEO Sofia Svensson in an interview in Dagens Industri in November 2022. But a hidden recording from inside the company from the fall of 2022 reveals a design flaw that the company chose not to tell about. "We ship out what I call... unsafe Chieftains", a consultant is heard to say when the CEO and Deputy CEO are present. Hear the recording from inside Hövding in the clip above. Problems with the power supply Hövding's technicians have concluded that the root cause of the problem is so-called fretting corrosion, which can cause problems with the power supply from the battery. On the recording from last autumn, it is also discussed that customers who advertised helmets are replaced with helmets that have the same type of fault. The vice president expresses that "we have no other choice". - I personally think that the helmets should have been recalled. This is how I think the safety of all cyclists should have been handled, says customer Ricardo Tarrida Thuré. Here is the like to the article in Swedish: https://www.svt.se/nyheter/granskning/ug/inspelning-avslojar-tekniskt-fel-som-hovding-dolt

Is it reusable after an impact?

What size is it?

Can I use the Hövding 3 for the e-scooter even if the scooter only goes 20 km/h?

How should the following statement be understood? "The airbag is easily charged via a USB cable and then offers you safety for 15 hours of active cycling pleasure at speeds of up to 20 km/h." what happens if you ride faster than 20 km/h? long downhill rides, even urban ones, can quickly reach 50 km/h. is the product suitable for this?

Does this thing only work once, or can you fold it up again and use it again?

Has anyone already tested it? You can only return it unopened and I would hate to spend 300 CHF on something I'm not even allowed to try out. Is it legal on the road in Switzerland or can I replace my bicycle helmet with it (for an S-pedelec)?

The Hövding 3.0 seems to have a much more protruding "flap" for the zipper compared to the 2.0. In photos, this seems to press / rest against the throat or chin. This would constantly bother me, which is why I am considering the 2.0. Does anyone have experience with both models? Or is it possible to bend / fold in the flap in a reasonable way?
