They told me it's the HDMI cable and said give us $30 and we will send you a new cable.
First of all I replied no way am I paying for it, it's still in warranty, they relied it's a consumer part and is not part of the warranty!! WTF.
I asked if it would void the warranty by me opening the HMD to fit a new cable, and they did not give an answer to that.
I also asked would the replacement be a better quality cable - answer is no the same type, WORRYING.
I bought my original 4K in June 2017 and when I got it I was a bit perplexed that the image was not as good as I was expecting and the lenses were blurry in the centre, so I first contacted them about the blurry lens problem, they told me it was because I needed glasses. I don't normally wear glasses but I am getting on in years and have noticed my eye sight is degrading, so i got some glasses.
The glasses did make the centre a little better but then the rest of lenses were blurry ( I never noticed this problem when I tried the rift and the vive just before I purchased the Pimax ).
Then I read on this forum that they had sent the wrong headsets out, BE not 4K, and low and behold I had the BE model. This it's self turned into a hassle getting it swapped for the 4K model that I had ordered. This mistake by PIMAX ended up costing me over $30 for shipping that I never got back. I could live with that, but now they want another $30 for a faulty cable ( and what happens if the cable is not the fault. How do know for sure ). I feel like they are taking the piss.
I looked at Gearbest returns policy and I could send it back for repair only but then I would have to pay the shipping cost, over $30.
I payed $399 in June 2017 plus $30 shipping to get the BE swapped for the 4K model that I ordered ( wich took quite a while before i got it back ) plus ANOTHER $30 if I take ANOTHER gamble on purchasing the cable, at this price guess how much I wish I bought the rift from Amazon, which I could return no questions asked.
I just don't have a clue what to do for the best. I think I will probably drop it in the bin and learn a massive lesson DON'T BUY DIRECT FROM CHINA. They don't care and it will cost you more if you have any problems.
There should be dedicated a place on this forum where people can say what problems they have had with the headsets so anyone looking to take the GAMBLE can at least do it with a bit more information from the people who have already had their fingers burned.
Sorry for the long winded post but thanks for listening.
Edit - just had a message from @pinate, he has gone through the same hassle and now his pimax is just sat in a corner. So sad this is how they treat people that believed in them.
