Oh man, @sarah_patel25, my brain shuts down the second I see a spreadsheet, so I'll just trust you on this one lol.

My uncle ran a shipyard for forty years. He taught me to weld by saying you have to lead the puddle like you're herding it. If you just sit there and watch, the heat spreads out and you get a weak, wide bead. A little push keeps it tight and drives it deep into the joint. Letting it just happen is how you get a cold lap.

Oh man, that's the worst feeling! I got burned last year on what was supposed to be a variegated monstera node. Paid a ton and it just pushed out a regular old leaf. Makes you want to just give up on buying online, doesn't it? I've had good luck with the shop Green Canopy since then, they send real photos of the exact plant.

That rush fee basically paid for double the work.

Hold on, 18 months isn't that long. I've seen wired systems go a full decade without a single service call. That battery will die at the worst possible time, and then you're stuck.
