Got these to use in the prop shaft of a model boat first impressions they seem okay the only comment I have got is there seems to be quite a bit of play in the joints but time will tell if this will be a problem  ,they come with some spare grub screws and an Allen key for fitting I will give a further review on these as and when I have used them to see how they perform
