This article is very functional and fits very well to the EOS 450D. A little pity, I find that the manufacturer it requires such a high premium. The production costs of this part are certainly not so high that it justifies the price. However, since it was not my camera, but the friend I was going to buy him the original again, otherwise would be a cheaper choice.
Attention, there is no the item pictured, under the heading "Canon" is still the imprint "Supersonic".
