I was sceptical at first since I did come across a site emoment.co.uk which promised cheap in car cameras, they had a paypal approved logo, I ordered one and it was a scam! Never got the money back. Take heed, do not purchase from this site! Just check out the site contact details (enough said!)
Anyways, with this product I was simply happy with it, the delivery time in all I think was about 2 weeks, from China, that's not bad! The packaging was tops, everything that should have been included was.
It comes pre-tuned to Russian language, which i kind of expected since their insurers kind of demand they have cameras fitted. After searching on Youtube I found out how to access the Menu and easily switched to English.
For the price, it's WELL WORTH IT!
Negatives: The GPS plug in is VERY difficult to get out once in, and often the wires will tear on attempting. SO just leave it in you're thinking, the only problem is it drains the battery even when the device is switched off. Problem with the battery being drained is it then loses the date time info so you'll have to go through the tricky menu and procedure to set often.
