Custom Service: Amazing - near instant response on twitter with all my questions answered and really helpful guidance Price: Incredible - The chairs in the offices I work in are near 4 times the price of the AK Racing MAX I bought and don't hold a candle in comparison Delivery - So damn fast - I had my chair in a few days amidst all the choas of Covid-19 where everything else I ordered was delayed by weeks I've had 10 years of mild/annoying back issues and they cleared up within 2 weeks of getting my chair I feel like an advertisement but genuinely, amazing
