I have been a DIY enthusiast for over 40 years. These are the cheapest, most useless molly screws I've come across. The extension assembly broke during installation, even when my cordless screwdriver turned it to the lowest torque setting. An adjustment to prevent the screws from being driven too hard into the drywall. Under these circumstances, the expansion board should NEVER break. This left me with the UNFUN project of digging the rest of the assembly out of the wall before proceeding. My recommendation is to avoid at all costs.
