Strengths: Will do 2 really mucky bikes on one load,really easy to use,plenty of cable and hose,won't damage your bearings
Weaknesses: If you try and squeeze as much water as possible into it, it will leak in your boot through the breathe holes in the cap.I suppose it's expensive when you think you could clean you'r bike at home for free but personally i think it's worth every penny.
Overall: Mine gets hammered in the winter and it cleans the bikes good enough until you get them home to wipe them down with a cloth.Me and all my mates love it and take it with us every time in the winter.
Weaknesses: So expensive ,even the extra's like helmet mounts are dear
Overall: Fantastic light output has'to be seen to be believed,so light ,mine has exeeded it's burn times on many occasions.I am really pleased with this light,i have seen quite a few other lamps but nothing anywhere near as bright as this.Awsome.It's a shame it's so expensive but put any £200 light next to this and then you'll see what your paying for ,shop around and you might be able to get yourself a bargain like i did.
