I needed a friction lever for a Manfrotto 504hd fluid head and am very happy with it. It's definitely a little pricey, but it's very well made and really fun to use with its ball mechanism that gives you a wide range of settings. I connected both lamps and a monitor to it and it worked great. The only reason I'm not giving it five stars is that it's definitely expensive for what it is. If it was about $20 cheaper I think it would be well deserved.
