I purchased the earlier version so that I could have my flash centred over my lens when shooting in portrait orientation - mainly so I could use fill-in when shooting catwalk. The problem is the bracket puts the flash on the wrong side - when you hold the camera so the flash is on top your hand is in the underneath position and that is very uncomfortable. For a while I persevered by mounting the whole thing the wrong way round and turning the flash head through 180 degrees. It would just about work but you lost some of in in-built functions on the flash. I recently purchased a Custom Bracket CB Mini-RC and it is ideal. You will still need to purchase an Off-Camera Shoe Cord (which comes with the Speedlite Bracket) although there is an interesting alternative made by Nissin which gives you an off-camera cord together with a second hotshoe on the pentaprism.
I certainly would not buy the Canon Bracket - and I am normally a very dedicated Canon user.
I hope this helps.
