I've been using the same tiny square of black electrical tape for nearly 2 years without issue, just slides across when needed, the tackiness hasn't noticeably degraded in that time, it's barely noticeable to outsiders unless they really look for it and it hasn't let me down yet. When it does let me down, it basically zero cost to replace and it definitely won't crack my screen either :)
