Yessir, they have. First, an apology, postage
wasn't free, that was due to a misunderstanding with the German-to-English translation on the web, so it cost me a further 9.90 euros. The company I dealt with were extremely friendly and efficient and I'd recommend them.
I was slightly disappointed when the items arrived to find they were fixed with anodised screws through an anodised steel plate, I was kinda expecting/hoping for stainless. Also, the screws are self-tappers and fix into the plastic housing of the reflector, whereas I'd have preferred a threaded steel insert.
That said, because they are a Shimano product and designed to fir these pedals they look very good thus far, nestling nicely onto the pedal and looking very much like they won't get in the way at all when using cleated shoes.
I haven't actually used them yet as I was waiting for payday before purchasing a set of shoes, but as this happens Monday I will be able to report on how I get on, both with the pedals and with being clipless for the first time (ulp!)
I can try and post some pics of the pedals with reflectors fitted if you wish?
