Contrary to some fakes (Neewer), the width of the rail corresponds exactly to reality. Others may be narrow and if you have a slightly wide clamp they may not tighten. The finish and finish isn't up to scratch. The Neewer is actually much nicer (but it's a bit narrow despite barely tightening all of my clamps). I have a pair of Sunwayfoto L brackets and they are very good so I was surprised by the roughness of this piece. However, it has a handle for tightening fine threads. Again, some of the cheaper versions use row threads. The reason I returned mine was because the bottom rail didn't extend the full 200mm. Look closely at the side photo. If your anchor point is close to the camera, you won't be able to move the rail forward far enough.
