Waste of money
Bought this exact unit on for [$]. It broke on my second outing. Specifically the cheap plastic clamp broke. Fortunately I had some tape with me and was able to keep it attached to my tripod arm during the shoot. Didn't get any satisfaction from the seller, so I bought a second for [$] (I know I'm a sucker for a low price). The second has not broken it's clamp yet, but the zoom control is very "notchy" and does not allow you a very smooth zoom. Spend the additional money and get something decent, not a Chinese import. I know I will.
