It's a good mod, I have one. Not bothered trying TC as got 4 DNA squonkers for messing with. The Rage is a good, solid mod, only downsides for me are proprietary bottles & anything over 25mm overhangs. If you find it around the £60 mark it's a bargain as £100 on release.
Pull the ring on the bottom down & twist the bottle left & right before pulling down. I've had no issues getting it in & out.Not long back from holiday but I got the rage before going away - Brilliant mod but the bottle oo jesus I checked to see if I had the double o ring issue and I dont yet the bottle still take a beating to get out its at the stage im worried im going to rip the bottom of the bottle is there a knack to putting it in and out properly?
