Was gonna buy the SWM C20C, but as DinoDirect couldn´t deliver I got refunded and found other lights that looks interesting too, so lets hear your opinions!
While the X10 only has two modes, it's built like a tank. The tail-twisty operation turns off some for sure - but it is dead-nuts reliable.
I don't own the Shadow, and therefore cannot comment on its attributes.
More compact and pocketable.... For the price I'd go with the Shadow JM07
The SWM C20C is a great light, I wouldn’t pass it up. Not as small and powerful as my ZL SC600 but still a great light for the money IMO.
Can't speak to the 4Sevens, but the JM07 is a great light, one of my very best. whokilledJR has a great review on the new version, with comparisons to the old:
I bought the X10 and I´m really happy with it!
Own the ZL SC600 too and the throwy X10 kinda compliments it, and they´re both built like tanks.
