Be careful of what you buy.
A couple of years ago i bought a set of genuine mounts of Evilbay. The seller is a pretty well known seller from overseas, saved about $20.00 on buying genuine from Australia. Anyway they arrive and shock horror they were a generic brand. When i sent the seller an email containing pictures of what he supplied compared to genuine mounts , with LR Markings. The reply back was along the lines we cant be held responsible for what our supplier sends out. Send them back at your cost and we will see what we can do. Saved $20 bucks cost me another $500 ( Estimate) After changing the mounts twice within 18 months after buying oem, genuine only for me worth the money and so much better.
