The slate is of good quality, excellent grip from the bottom so that it does not run and an excellent and strong magnet for the screws to stay stuck.

s someone who frequently needs to repair laptops and iPhones while mobile, I've been looking for a product like this for a long time.

Decent product. Magnets work good but is a little pointless.

The iFixit Magnetic Project Mat isn’t just for tech geeks—it’s a multitasking marvel! This 8x10-inch mat lets you jot down to-dos, reminders, or doodles with the included Staedtler pen, then slap it onto your fridge or any metal surface for all to admire. Its magnetic magic keeps screws and bits in place if you’re tinkering, but also doubles as your quirky grocery list holder. Writing’s a breeze, erasing’s even easier—no smudges, just smooth wipes. Lightweight and grippy, it’s a fidgeter’s dream to handle. For $20, it’s a fun, functional sidekick for your chaotic life—though I’d love a neon version to spice up my fridge even more!

I suppose any magnetic surface would work, but grids make it easyt o remember where fasteners came from in the device you are working on. My only two complaints are that it is smaller than I anticipated (I never read the size description so my fault) and the pen has no way to be attached or tucked into the pad. That's going to disappear soon. Other than those two things, I love it.
