I have had a trap door for 3 years and I love it. The noise factor should be solved by the new delrin launcher on the Mach 4 but I am shooting older model. I have read a lot of people on the forum cuss the Trap Door, so maybe I just got lucky or my shop set it up right in the first place. I have never changed the adjustment on it even though I shoot 60 to 70 # depending on the time of year. I am upgrading next month to the Mach 4 just to get the less-noisy launcher. I would recommend but I could be in the minority.
