Very easy to fit - You just have to take the bolt apart and fit the orings over the tophat section. I haven't used them, but yeah for optimal performance you will need to change the dwell and LPR.
I'd leave the dwell and LPR alone to start with and just change the HPR to bring your velocity down. Some users report they can lower their LPR but let everything settle for a bit first.

What they are supposed todo is make the marker more air efficient.
The way they do that is by using 1 or 2 on the top-hat orings on the top hat of the bolt. By doing this the marker uses less air in the process of firing.
If you have time to setup the marker correctly, then they are good.
You can do the same job with hose or electrical tape- all the mod does is reduce the volume of the dump chamber that stores air for the shot. Less volume of air means you need a higher HPR pressure to compensate so you end up with a matrix that might be a touch louder and a smidge harder on paint but will get an extra pot or two. Just fit the rings making sure they don't end up blocking air passages etc and then chrono to suit.
