Honestly, I've learned that lesson the hard way too.

Ever check the actual settings they test with? Margaret_gibson70 has a point about the data, but sometimes those battery tests run the screen dim as hell. My last laptop crushed the review score but died in two hours on my normal brightness.

Yeah, simons12 is right about that sucking the life out of it. It's not just bricks either, anything porous will wreck your mix if it's thirsty. I see it like leaving a door open - you're just asking for a weak spot. In my line of work, that's how pests get in, through the gaps you didn't mean to make. A solid bond is a solid bond, whether it's mortar or anything else.

Skimming the book is lowkey cheating. But fr who hasn't done it? Just don't make it a habit.
