A part of the review has been auto-translated.
Because there is no built-in battery, it seems one must set the date & time EVERY TIME the dashcam is switched on! That is ridiculous - especially at this price point! It should at least have a small 'button' type battery to maintain the date & time (not having a battery is advertised as a 'feature' - because it reduces the risk of explosion!) What is the point of having a 'Record when Powered On' facility (that starts recording as soon as the ignition is turned on) if one has to reset date & time?
The hardware: makes a good impression first. The connectors can not be connected incorrectly, everything is itself without instructions (unfortunately only available on paper - on the included mini-CD as PDF would be an idea!) to connect and install easily. Well, I guess you've thought about a lot of things, but this is where the positive ends -- unfortunately. Video quality: rather poor, even in the highest possible resolution. One would expect much more in this price segment as well! I don't think the resolution data are correct, it just can't be! Software: a total disaster! First the program for formatting the memory card: only in Chinese characters. Please to the manufacturer/seller... Think about it: there are people who can't do anything with it! But luckily still has funkioniert - but just, only with luck. The image processing software: this is absolutely unfit. This is partly possibly also due to the hardware-side software... GPS and Co: simply not available - supposedly I did the test drive in Hong Kong - but I have never been there before. Here the buyer is imagined something in the item description, which is obviously not so available! Conclusion: better quality with associated price buy from well-known manufacturers! This stuff here is good at most as a crash-record, nothing more. Unfortunately.
