I originally ordered the wrong sized bearings. A quick call late Friday afternoon to Simply Bearings and the correct bearings were in the post and arrived Saturday morning - amazing service and very very friendly and knowledgeable staff - If I could give 6 out of 5 I would.

I had thought it would be difficult to get bearings for an old eggbeater drill. To my complete surprise Simply bearings had what I was after and delivered them the next day. Excellent service. So much so, yesterday I ordered a couple of deep groove bearings for my band saw they arrived this morning. I don't have a lot of need for bearings, but when I do, I will use simply bearings.
