This Daily Mail article and the video evidence why a dashcam is now essential. Moment biker pushes moped into a car 'in insurance [problem]' http://dailym.ai/2uhkhbz

In May 2015 I purchased a Snooper DVR-3HD dashcam from Amazon sold by Amazon in October this year it developed power related faults including turning on, battery holding no charge etc I returned it to Snooper via their technical support who recently emailed back saying that although it was out of the 12 month warranty (I'd owned it 1 year 5 months) it was not a model that they stock anymore and that they do not have spares for the device and therefore cannot repair it. They have therefore offered me a newer model the DVR-4HD at a discounted price of £99.99 instead of the regular RRP of £149.99. However I do feel that although this is an upgraded model I feel it is only giving me the option of paying £99.99 for a replacement direct from Snooper and if I don't, then I am stuck with a faulty dashcam which I have paid £139.99 for and lasted only 17 months. Obviously there is the issue under the Sale of Goods act of arguing that goods must be fit for purpose for up to 6 years and I would consider a dashcam of that price to be more towards the higher end of the dashcam market compared to many other cheaper models and therefore expect it to last longer than 17 months before being faulty and then unable to be repaired. The SOGA also says that the claim should be against the retailer (Amazon in this case) but it is Snooper who have dealt with the repair via their technical support and have not exactly told me what the fault was yet. Should I be directing my claim towards Amazon instead and should I be requesting either a replacement or at least a partial refund from them seeing as it can't be repaired? Or is it fair to consider that a £139.99 dashcam can be classed as "dead" after just 17 months (i.e. only expected to last that long), or that £99.99 is a reasonable price to pay for a replacement model which now retails at near enough the same price as the old one when effectively the only main difference between the two is that the new one would be at the start of a new 12 month warranty?
