Couldn't contact seller directly - no valid item number.
Did a return via ebay, with freepost label
Email from seller offering 50% refund on £6, despite item page stating 30 day returns, and the image being misleading.
"This one can be used instead of Shimano. We are very sorry that our description made you misunderstand."
'Would like full refund please'
'OK, sorry for you problems'
edit.
