FYSETC 3D Printer Magnetic Build Surface A Plate, 300X300 mm/ 11.8X11.8 in Upgrade Flex Magnetic Hotbed Build Plate for Steel Spring Surface Sheet for Reprap CR-10 10S MP Maker Pro Lulzbot Ta

Not as large as advertised

I bought this to replace one of my worn out "A" section magnet sheet and the magnet is very weak and when I try to 3d print a 21 hour product the sheet slid right off and wasted my filament threading out like a wig of hair. I found the sheet on the floor. Will not recommend buying this brand. I have had other brand that had better magnet strength.
