Went from ~3 mph on the wall outlet to 25+ overnight. My wife stopped asking every morning if the car would be ready. That single question disappearing from my life was worth the install cost by itself.
I dragged my feet for a year. Told myself Level 1 was fine because the numbers technically worked. What I didn't calculate was the small mental tax of watching the percentage climb slowly every night and doing "will I make it" arithmetic before every unplanned drive.
If you're on the fence about upgrading, the answer is just do it. The tech is boring, the wire is boring, the install is a Tuesday afternoon. The relief is the whole product.
Anyone still on Level 1 by choice after having tried Level 2? Curious if there's a real case or if it's just "haven't gotten around to it" like I was.
