Man, I think this is the inconsistency of the manufacturing process. Lucky MR let Hasbro got the license or I will be biatching to MR about this.
The farting on this ANH Vader is comparable to the humming of my Obiwan which is the softest I've got.
My ROTJ is loud but flat compared to the others, loudness 3rd to Mace and ANH Luke which is LOUD.
I tried the Maul in the shop before but I don't hear the crisp farting sound. More like a normal humming which was why I was concerned. BUT, the Maul's batteries were very very weak when I held it and very soft.
Overall, I really like the ANH's crimson blade very much. Looks awgasmic in the dark, brightness comparable to ANH Luke with little blotches, ok, just one. Never seen red this.... red, like that except for neon signs. Its Ferrari red but glows! :D
Once I get all the 10 FX. I will start posting pics.
Btw, Owen, I already took the first step to V2'ing the ROTJ by stripping the yucky gold paint. :D
