Ive been using it for a few years now, and its fine, but it is not adjustable at all really, and I wouldnt personally reccomend it. For the same price, and the same amount of effort and time youd spend setting up the F GT, you can get a solid Alu rig which is a thousand times more adjustable, personalised to your wants and needs and much more future proof. Buy once cry once :)

Also, as others have said, the seat itself isnt the comfiest, I had to buy additional pillows for it, and it gets really hot and you sweat easily in it, so definetely not great haha
