Got this mount as an alternative to the quadlock stem pro (which has notorious issues with the ninja 650) in light of this the evotech mount is 10 fold better HOWEVER I did have some minor difficulties actually getting it lined up - you have to seriously crank it to get it tight n snug during this it has a tendency to slip slightly right (unsure if this is due to the turning of the bolt or the design of the ninja stem) so in the end it's a solid well built peice but my phone ended up being slightly off center (granted I could probably fix this but I was borderline stripping the bolt tighting it)
Definitely would buy from evotech again can't remember last time I had a product this good feeling in terms of quality
