I lost my clip ProTool 300. I bought this model with accessories: everything sucks! A branch of the clamp can be unscrewed regularly, the case allows to put a maglite, 1 replacement blade but not the additional threaded ends! Poor design, poor quality ... Difficulty: it is quite big, very heavy in his belt, and when to tighten a bolt, do not be afraid to keep the memory in the palm of his hand.
