my dad literally surprised me with a matching bronco last week and i'm still in shock. it's beautiful. but i hike and camp a ton, and after my first trip yesterday i realized the plastic on the side of the trunk area is going to get absolutely destroyed by my gear and muddy dogs.i've been searching for a cargo liner that covers wheel wells completely so the plastic doesn't get gouged. most of the standard ones i see just cover the flat floor and leave the sides totally exposed.i found a couple brands like canvasback and 3w that seem to have extended coverage, but i'm hesitant on how they actually attach.

does anyone use a cargo liner that covers wheel wells and stays put, or do they just slide around and look messy after a month? truly don't want to ruin this truck.

okay so my old conair finally died and literally every single corner of the internet is trying to convince me that i need a high-speed hair dryer because it "saves time" or whatever. but like... thermodynamically speaking?? heating elements can only get so hot before they fry your scalp right? so if the max temperature is basically capped by human pain tolerance then what actually makes a high-speed dryer faster than a cheap one? is it literally just that the brushless motor spins at like 110,000 rpm and blasts the water off your head mechanically instead of evaporating it? because to me that just sounds like a regular hair dryer but louder or with a tighter nozzle to fake the pressure. idk tbh. i asked a stylist and they said it "protects the hair cuticle" which sounds like absolute marketing pseudoscience to justify a $200 price tag. can someone who actually understands fluid dynamics or physics explain if there is a real mechanical difference here or if we are all just paying a premium for a smaller motor that fits in a prettier handle?

because i am genuinely hovering over the buy button on a laifen air right now but the cynical part of my brain is screaming that a fan is just a fan at the end of the day. what is the actual science here?

A Wolfbox MF100 replaced canned air for my PC cleaning and the first test on a dusty 360mm radiator was stronger than expected. It cleared the loose dust fast, but the airflow vibrated a loose fan extension cable right off its header near the GPU. Nothing was damaged, but it made the duster feel less like a harmless desk blower and more like a real tool.

For anyone using electric dusters on PCs, how close do you get to the PCB, and do you stick to low speed around connectors and fan headers?
