If I were buying again, I would definitely not overlook this part, because storage quality affects performance a lot.
Installation and Daily Use
In my opinion, installation should be straightforward for any dash cam, and this one is manageable if you follow the instructions carefully. Once set up, I found daily use pretty simple.
