EUC safety

Hey everyone, so I’ve had a Onewheel pint x for about a year and a half now and I’ve been looking to upgrade. I’m looking at the Begode falcon or t4 pro. The only reason why I haven’t bought one yet is because my gf is very very concerned about the safety of the device. She thinks since the max speed is about 20mph more than the Onewheel, the bigger battery, and apparently she has said that a decent amount of them have just fell randomly. With this she’s telling me that it’s a lot less safe even with the gear I have right now. Any tips or statements to make eucs sound safer? Thanks a lot.
