I don't have too but I do. It's either a lanyard or a little plastic clip to which my shirt doesn't have a good place to put it.
I'm using a Bebop one that I got from Vintage Stock. It does get in the way sometimes.
Now that's where my blower motor is. I had to replace my blower resistor and since it was inside the car, I got to do it while it was raining.
4 screws for the glove box and 2 screws for the resistor. Wish everything could be that easy.
I need to reseal my cabin filter. I notice the driver side floor gets wet when it rains and the filter just happens to be under the windshield. Not hard to get too, though. Just a couple of screws.
I never let mine get so low that I think I may run out. I don't know how some people are comfortable letting the needle go on empty.
I mean, I'm sure my car would last for a bit on empty but why chance it?
I use only the thumb of the hand I hold my phone with.
Needless to say it takes forever to type anything like that. I really should start using both hands.
