Does anyone have any experience installing and/or using this boom brake?

I don't know how much you have looked into them so I'll give you a basic description. The big black brake thing that hangs off the boom contains a couple sheaves that when the line is run through them generates friction which is controlled by 2 means. The brake system itself has a twist knob which adds or relieves pressure on the line passing through the sheaves. You can crank that down to basically stop movement for a Preventer function. The secondary adjustment is the tension you can put on the line itself which will have a lesser impact on the friction on the line passing through the brake assembly.
I have had 2 of them installed on 2 different boats. Although they were both pilothouses the installation was a bit different. My first one on a Nimble Arctic 25 was set up with the assembly line running over the forward cabin and secured at the slotted gunwales which was a bit of a tripping hazard.
On my Nauticat the line is secured to the SS grab rail (six foot long 3 point attachment to the pilothouse roof and very secure) at the port forward end of the pilothouse. It runs up to the boom and down to a block at the starboard forward end of the SS grab rail and then back along the SS grab rail to block cam cleat setup at the aft end of the rail which is easily accesable from the cockpit. I usually just have the brake exerting a little friction on the line and if I want more I pull the line tighter through the cam cleat. If I want to crank down on the brake itself for a complete Preventer function I can reach it from the forward cabin roof so I don't have to go up to the pilothouse roof. It works well for me and is out of the way up on the pilothouse roof where the 'tripping hazard' is not such a big deal because if you are up there you are being damn careful any way ;)

Yes. I've written about it on my blog. It is a pretty decent piece of gear, if a bit large and clunky. Fairly easy to install, and easy to use.
Thanks Stan and Sailingdog. Stan: So you didn't secure the lines to chainplates? Sailingdog: what's your blog address?
I had one on my F31 and it worked great, ran lines to chain plate and tackle back to cockpit. I then bought the biggest one for the Tayana 55 but it is hard to get a big enough shackle to attach it to the boom. I have bent two of them open.

There is a no moving parts Wishard one too, but it still has a shackle.

Nope. That would have led to more complicated line runs and the whole idea of the Boom Brake is to Slow and Soften the blow. If I was just hooking up a free running ... whoosshhh..... Booom !!!! .... line to save the sail control system in an unexpected jibe .... sure hook it to the strongest thing on the boat, but the Boom Brake's friction dissipates that rig shattering force buildup. If my chainplates happened to be in the right place sure I may have used them but for my relatively small main I'm not at all concerned about my attachments.
