I did some digging on the manufacturers website and for their metric products I found the following PDF that calls out their strength in kN of holding for various surfaces:
A quarter inch is 6.35mm, so if you’re using say a 6x30 in gypsum fiberboard it would have a holding of 0.33kN or about 75lbs, which is generally what you’d expect from a plastic toggle.
Have you thought to reach out to Logitech? They may cover it under warranty? Checked on Logitech's website and they have a 1 year hardware warranty on it.
