I have four of the dual sided plates for my printers. I had purchased several other plates some cheaper, and some more expensive than Fulaments, however this one has by far outperformed the others (Wham Bam, Creality).
The surface both stuck well without having to use hairspray, glue or other to get print stick. Prints released easily from the plate. The surface has held up well after almost of year of constant use, and still remains flat. Other flex plates I have had to use binder clips on the edges with large prints because the flex plate was not sticking well enough to the magnetic bed, and would curl up on the edges. I have not had that same issue with the Fulament flex plate.
