Never too late to get proper micro SD. You wouldn't want them to fail when you needed them the most.

That's why once again, I would STRONGLY URGE anyone who's using SanDisk Ultra Micro SD.....Please avoid it at all cost. Use it for mobile phones or anything else EXCEPT dashcam.

Many times warned liao. The only micro SD you should be using is MLC and Samsung Evo Plus is what you need.

*Disclaimer
I'm not a Samsung products ambassador nor hater for SanDisk. Just giving some consumer advice for dashcam users.

Do what I do, stand near the petrol pumps as somebody finishes pumping petrol and as you see the receipt coming out of the pump, rush in, yelling something stupid but non-threatening to disorient the guy and rip the receipt from the pump. Then proceed to counter to get the voucher. If he chases after you, just give him back the receipt and apologise profusely but if you act crazy enough, most of time they won't. Warning: do not attempt this with women. I'm still hurting.
