Just want to share my very positive experience with Blackboxmycar.com (Alex). This guy is simply amazing. Some vendors should take a lesson from him on how to do a great customer service.
and
I purchased my Blackvue DR400G-HD last summer through a group buy. Alex was able to answer all my million questions before the purchase, responding withing minutes. Then, after the purchase, he provided all the technical support to help me install it, and made sure everything worked. Six months later, I was having an issue with my Blackvue and I wrote Alex for help. And again, he took no delay in coming forward and resolving it for me.
Overall, I am a very happy customer and would recommend him to anybody who's considering getting a dashcam. Also, Blackboxmycar is an authorized reseller for Finevu and Blackvue here, so you get a full warranty support as well.
BTW, had a chance to meet Alex in person, during my trip to Whistler - he's a nice guy in person.
Cheers!
