Pre as I haven't used them yet they arrived on time, clean and undamaged, packed in a fairly sturdy box. You look decent. And they have wire mesh for support on one side, which isn't clear from the pictures, on the same side as the cardboard grid. There is no grille or cable on the intake side as you might expect. They seem to be as durable as any decent filter. Unforeseen quirks aside, it certainly appears to be a good quality filter at a lot more affordable than the bigger established brands and I'm glad I found it. I don't find the MERV 8 or MPR 600800 a good middle ground between overload. on your blower and actually does some useful filtering. But with an oven in a dusty basement or in less than ideal conditions I think it starts to pack up and needs to be replaced up to 3 months regardless of the brand.
