My experience of INKA
I bought the first set for my 2013 7 seat Beach directly from INKA and quoted the club discount which I got although at the time it wasn't any cheaper then amazon, they fitted fine.. although they came with no labels at all, others I had seen had INKA tabs I had always wondered whether they where seconds..
The second set I bought this year for my 2015 SE through the club, was the cheapest place with the VIP discount although at the time the Kev was on holiday and wasn't back for a few days and I had wanted them for the weekend, he/Martin suggested phoning Inka to see if they could help get them in time which was kind of them. The guy at INKA said he could get them to me before the weekend If I paid full price, I asked for the VIP discount to which he refused and was quite blunt about it (despite it being repeat business and being explained I had the permission of the club). Luckily Kev was back day before the break and he lived on the way so he kindly agreed to meet at his house and I got them at the VIP price (he also leant me his Cali Topper which was result!)
This set fitted fine including the latest head rests and they all had the INKA and Airbag tabs the last set didn't have.
As for feedback I have to say I've been disappointed with this set and I think It is because I have the factory Leather/Alcantara seats. They seem to slip around and ping off the front seats seat bolsters. I have to adjust them every time I get in and out which is frustrating. I don't remember having this problem with my cloth seats in the Beach. I think the guys attitude on the phone at INKA has also tainted how much I like the covers and any patience I may have had for them has gone.
