It's a good light. But the iTP A3 EOS and its Maratac AAA twin cost about half as much, and come with better clips. The iTP version has a better keychain attachment than the Maratac. But the Maratac is better if tailstanding is something you'd prefer. Shipping charges on the Maratac version can be steep from County Comm (only place that sells the Maratac version). So unless you plan on ordering a variety of items from County Comm, best to go with a site like goinggear.com that sells the iTP version with much better shipping rates. I'm currently carring a 4Sevens Preon model. I got the black, kit, version that includes both AAA and 2AAA bodies; along with the reverse-clickie switch and the seperate top to convert it into a twist only light. I put the twist top, for lack of a better term, on the 2AAA body. Works great! But you can also use it on the AAA body too. I might be wrong, but I believe that the AAA versions of the Preon are sold as twist lights, when sold seperatly without the 2AAA bodies. Honestly, since the LD01 is basically a Fenix L0D but without strobe and S.O.S. modes, the iTP/Maratac lights are a much better value since they too only have medium, low, and high modes.
