I know this has been stated before in this thread, but it bears repeating: be very mindful of the screws in these, if they come loose at all make sure to tighten them immediately. One of the screws at the base of the handle came out for me and I spent 15 minutes combing the ground for the screw. Someone further up suggested using superglue to ensure the screws don't wiggle loose and go flying mid-twirl.
