Hi Swarga,
Thanks for checking us out. We are new to Dash Cams, but have been doing e-commerce for almost 10 years. We do sell the Blackvue and the Lukas (the Lukas is on sale for $235 now) as well as the DVR 207, GS1000 Orange Menu and the F500LHD. We are authorized dealers for Blackvue and Lukas and have personally met with both companies in the last few months. We are in talks with several other Korean/Taiwanese/Chinese manufacturers to broaden our selection.
We have a 30 day return policy and honor all warranties (ship the items back to us not Asia). We also have a technical support staff which you can reach by calling our toll free number during office hours.
Please let us know if you have any more questions!
Thanks!
