Eric B. (Staten Island, US)
SD card

I called up about my dash cam not working properly kept starting and stopping. They diagnosed this over the phone and told me my SD card should be replaced. They were very helpful on the phone and ordered the card right away and that was the problem.

Service at BlackboxMyCar Canada

What I bought and everything about the product is great...What is even greater is the service. Follow-through is one of the most important concepts many companies lax, not BBMCC. OH Ya, I will be back! This was given a 5 star, but they need a few more!

Vroom (Vancouver, CA)
Saved the day!

After 5 years my SDcard decided to stop recording. Went by Blackbox and they had me up and running again in a matter of minutes.
