i bought an IFE2 a few months ago and thought I'd share my impression of this light. Overall the light is as expected, high quality, bright and the magnetic control ring works as advertised. I was trying to find one flashight that could serve many purposes from looking for something in a closet to walking the dogs or camping for a weekend all the way up to tatical use. I'm happy to say that this light does it all very well. I have tried 3 types of batteries, 2 work well and one does not . An 18650 rechargable works great and has become the only one I use. CR123's work well also, RCR123's are too long and it is almost impossible to close the tailcap. My previous EDC was a gander mountian GSX220, so I will compare the two. Throw A big surprise here, the GSX220 wins easily. The GSX throws a smaller tighter beam quite a bit farther. The IFE2 throws much more light in a wider more usable pattern. The GSX will light up a doorway while the IFE2 will light up the whole front of the building. Pocket carry The GSX just makes it for pocket carry, the IFE2 is a little too big for me and I carry it on my belt. tail stand GSX so - so but it will, IFE2-no. Battery The IFE2 uses several types while the GSX is limited to only cr123's. Light levels The IFE2 excells here with the adjustable ring, GSX has 2 levels. I think both lights are excellent for the cost (GSX $29-39) (IFE2 over $100). I like the IFE2 enough to buy the IFE1 soon, trouble is when I tell someone that I am buying another flashlight they think I'm nuts and don't need another flashlight - (but I do) I hope this helps someone.
