I am glad the OT told you when ive been through it they didn’t tell me till the last second. I am only getting the q100r which if I got third party was £1500 which barely gets anything. I imagine you need a really supportive chair if you’re getting the q300m, as otherwise id say you could consider going third party and looking at the ottobock a200 which is 66 kg and can be disassembled and is crashtested. I couldnt handle that though as it wasnt as supportive as the q100r for me and I felt bumps far more.
