it depends what your expectations are. I like a really small light and carried a tag for a while, but the plastic was problematic. I finally got a br-435 powered light at target sold under the Eddie Bower moniker (Coast also sells a similar one. I unscrewed the head and replaced the stock LED with one from superbrightleds.com. Great little flood. The batteries are a PITA to find, but it is for intermittent use so they last awhile. The body and head are very robust and at 10 bucks, I don't worry about scraches from my keys. There are nicer lights, but they are expensive and I wouldn't want them banging up on my keys. It is read because the br-435 is a lithium with 3V availible -- not enough voltage to run a white or blue.
