Let's face it, for this price point we can't expect top build. The support it's sturdy, made of hard plastic. I've use it with a canon 550d and a lcd viewfinder, it works very good for the price (that's why I give it 5 stars, because although it's made of plastic, it's sturdy and does the job well done). Now I can have more stability in filming without a tripod and the versatility to move. This support works great when you're still, doesn't work well when you walk so don't expect a steadycam from this.
For this price point I can't honestly make this product better.
