I don't like giving negative reviews. The receptionist was really helpful but the people picking the bearings off the shelf were, if I was kind, unlucky. I asked for 2 sealed bearings and got one sealed, one insealed. The next two deliveries were unsealed so I kindly pointed it that the serial number on the box of sealed bearing was identical to the unsealed, so maybe not entirely the packers fault. After a special notice was attached to the order to actually check the contents of the box before processing I finally recieved a sealed bearing in the post. A sealed bearing. Not the sealed bearing. There is no maker's mark on it. Just a random bearing in a plastic bag with no box. I've given up. I'll fit the unbranded bearing and hope for the best.
