I was lucky enough to be able to test TBO's F8 trigger. Along with testing it for the stock optical sensor board i also tested it with the Seventh Element Miroswitch board. when i received the trigger it was very well packaged and i received it within 3 business days. when i received the trigger I was happy to see that Inside the package I found the trigger and trigger magnets held within a plastic ziploc bag that fit the trigger perfectly along with the 2 adjustable return strength screws.
To install the trigger simply remove the frame screws. Unscrew the trigger pin and both of the adjustment screws. Then pull out the old trigger and simply put the TBO trigger in its place. If you are familiar with how to disassemble of your marker it should not take more than a few minutes. One nice thing about this trigger is you can either use the stock return spring, or the included magnet return, or BOTH at the same time! one of the magnets is simply placed on the return strength adjustment screw on the trigger itself. The other magnet fits into the spring hole in the frame, and is
small enough that the spring can sit around the magnet and be used in conjunction. Simply superglue the magnet is place (center as best as possible) and make sure to observe proper polarity (magnets should repel). I tried using the trigger with the stock spring and found that it was stiffer than the stock. i then tried it using the magnet return and found it to be a lot smoother and much much lighter. the good thing about the magnet return is if you chose that you want to adjust the return strength you can eaisly do that by replacing the return strength adjustment screw with one of the other 2 he provides with it say you want a lighter spring return? Put in the 1/8" long. you want a harder return? put in the 1/4" long. and the third screw that was in the trigger was a 3/16"
The trigger worked amazingly well with my stock board and i feel that it is a must for all fusion owners. I have a Seventh Element board in mine so i had to CAREFULLY
shave the fang on the trigger so it would not depress the microswitch making it unable to fire. (NOTE IF YOU ALTER THE TRIGGER IN ANY WAY IT WILL VOID THE WARRANTY)
Overall the trigger is extremely well made. The fit and finish are great and the trigger didn't even need bearings. the trigger pull is much lighter and smoother and this is a must have upgrade for your F8
and now some pictures for your viewing pleasure

Side by side comparison (note that my stock trigger fang is shorter than normal because i had to shave it down for my Seventh Element Board)
