Peter, Manager
I got this safety device for my daughter who has recently started to drive. I like how
compact it is, and yet still effective. I expected something more bulky, but am pleasantly surprised.
The flashlight on it is really bright. It was bright even in the daylight! I love the flashing red light
option as well. I tested out the seatbelt cutter on some old cloth, and it works well. My daughter isn't
a paranoid parent like me (lol) and really loves that it includes a charger. All in all, it's a great
tool with a lot of handy options built into one tool. I'm really glad to have it!
