I tend to end up buying a lot of stuff for the car (and for this channel). Here are some of my favourite products along with the videos in which I talk about them.
Some of these are affiliate links so I will get a few pennies if you click them. Thank you!
For the car
Quicklynks Battery Monitor II
Monitor your car's 12-volt battery
I'd recommend this to everyone with a car!
I think my 12-volt battery is kaput so this device was recommended to me so I could log the voltage and see what was going on. So easy to set-up and use with a surprisingly good app!
