When Gear2 / Gera 2 Neo the edges are rounded at the outer edges of the display - here the film has to be simple small, as otherwise the foil permanently apart, dissolves, or dust and dirt from accumulating under it! Who applies the film precisely, will find that they will not loosen or raises - it sticks!

Conclusion: film is worth the price and served its purpose perfectly - the "Anfassfeeling" when you operate the SmartWatch unfortunately lost something!
