Review on Upgraded TBWHL Ender 3 Pro Glass Bed Clips - Swiss Clip Style for 3D Printer Glass Bed Chip - Durable Metal Small Picture Frame Spring Turn Clips - Compatible with Ender 3 Pro, Ender 3 V2, CR-20, CR-10 PRO by Thomas Henry

These clamps are advertised as clamps for the 3D printer's glass bed. That's not what they're made for! Be very careful! I scratched two of them the protective layer on the heating stage and closed the circuit of the heating layer. Luckily I was there when I started typing. A few minutes after printing, magic smoke started coming out of the control box. Loss of MOSFET thermal layer and main board (all stepper motor drivers soldered to the board were damaged). This false advertising has cost me a lot of money and could have cost me my house burned down. Look at the pictures and be aware!
