I've got two iPhone 5's that have each been replaced by Apple 4 times (I gave up on using mine, my wife's one is playing up yet again), my iPhone 4 was replaced 3 times, hers twice, my 3GS was only replaced once, iPhone 3 not but was stolen, the richest tech company in world can't make a product without a problem so I hardly think any dashcam manufacturer, be that us, Mobius or anyone else is going to be able to make a foolproof product anytime soon, all we can do is make things the best we can and try and constantly improve what we do, we get problem product from time to time, it's currently under 1% which by this product category standards is probably about as good as we can do, for the 1% that do have problems all we can do is make sure we take care of things with the least amount of fuss for the end user, we do always look at what caused any problem and what we can do to improve things, our products may look the same but there's a constant evolution with each production as we make minor changes
I think when it all comes down to it service and support are everything, I don't begrudge Apple for the product not being as good as it should be, or as good as I would like to be because whenever I have had problems they take care of it quickly and efficiently, even after multiple replacements my wife is still happy to take the next iPhone when it comes out
For dashcams I think the largest complaints come not from those that have had products fail because lets face it, every make and model will have some percentage of failures, but from those who don't get adequate support afterward, some of this is self inflicted I guess as a result of buying offshore, human nature says people will look for a bargain when they can, nobody wants to spend more than they have to, reality is though if you buy online from a different country there is often little to no after sales support and often no legal recourse should things turn sour, the consumer protections you might enjoy buying in your home market don't apply
The problem is increased when buying online out of China, the standard of product for export and domestic markets is not the same, even if it looks the same, I've yet to see or hear of domestic market sellers that employ 3rd party QC inspection services as is typically used on export product, there are sellers that knowingly ship product that doesn't work well as they know that returns are next to impossible and the sale is just a number, they're not building customer loyalty or a brand, they're just moving boxes
