Hopefully you will get your item but it's happened to me 3 times and I have had to ask for a refund.
I've not had any previous dealings with them, but the eyecup turned up thi morning. It's a genuine part in the green Pentax bag.
However, contrary to my detail, the FR type is for the K-5, K-50 range not the K-3 range.
It fits fine but the K-50 has a slider diopter so the FR type has space for that, where the K-3 type is FS and uses a wheel diopter and is slightly different.
