I like mine a lot but have had it only a week. What is one supposed to do with 15 quality little lights? You can't use them all that often but you can look at them and play with them. That seems to be what I do. Did I say that I like my CR2 Ion? Well, enough so that I ordered a second one yesterday (AlBronze) to go with my blue one. No hot spot is nice for a change-just a nice, even spread of light. The low is useful with not a lot of output but the high is really bright. The light seems to be well made and finished. I wouldn't mind less of a twist (another 270 degrees) to get to high but that's not a big deal and gives me more time to play with the light. Being pretty new to LED lights that's about all I can say. I DO like my Ion and am glad I got it.
