Thank you for the input. We will check!

The Marmitek Wireless Presenter WPR 400 uses a Class 1 laser pointer. Class 1 lasers are considered safe under all conditions of normal use and are compliant with the relevant safety standards, making them legal in most jurisdictions, including those with strict laser pointer regulations.

I can't share any experience, but according to the information I could find, it has the following: -Wireless presentation control -Digital pointer and highlighting -Zoom function -Media management -Advanced functions -Wireless mouse function (Air Mouse -Range up to 100m (outdoor) -Battery lasts up to 100 days -Works with both Windows and MacOS (software) Unfortunately, I could not find an alternative model in our range that fulfils the requirements. Either they are equipped with a laser or have no functions other than "forwards and backwards" or, as here, have many functions but with software.
