The product arrived and was faulty upon opening. It would not charge up at all. I checked the manufacturers website and followed the troubleshooting guide, but this didn't fix the problem. I found reports online that this was a known problem this this particular model. I contacted the seller through their website, but received no response. I then contacted them by email and requested a replacement, as this particular model was the one I really wanted. They tried to upsell me, and admitted there was a known issue with the model I wanted. I asked if they could possibly test the model I wanted on site, to make sure it was charging, and I'd be happy to accept that as a replacement. They agreed to do this. When I didn't hear back from them, I chased them up and was told that all the models held the same fault, but advised I could pick another model. When I did this, they tried to overcharge me, so by this time, I just wanted my original payment back, because it was becoming apparent that they were clearly a dodgy company to be dealing with. They then denied that they ever knew the product was faulty and denied trying to overcharge me. This is despite them admitting in emails that the product was known to have a fault, and them checking their existing stock and finding them faulty. Finally, they agreed to refund me, providing I returned the faulty item. Until this point, they had never mentioned returning it, because they were well aware it was useless. On 28 April they finally provided me with a link to a postal form to cover the postage, meaning I would have to break the lockdown of the time to go to the post office, whilst suffering from poor health. I eventually felt well enough to venture to the post office towards the middle of May and sent the product back using their tracking postal form. Royal Mail Tracking confirms that this was signed for by them on 15 May. Since then, I have heard nothing from them and they refuse to answer my queries through their website. I've emailed each week and have received no reply. I have now had to open a dispute resolution with PayPal, which, to date, they haven't engaged with. They are still selling the faulty item on their website. Avoid this company at all cost.
