Should they have provided it with a strobe mode? I personally like to have a strobe mode, even if I don't use it often. It's truly bright on high, and I have no reason to doubt its 300 lumens after I compared it to the many (too many) flashlights I have. So, the mode sequence you will settle on depends on your goals and circumstances. Note that even a couple of minutes at high will start making the flashlight quite warm. I think this reverse sequence is a matter of preference, and you can always change it back to what it was. Now, whenever I turn it on, it starts with a high mode. You then turn it off by pressing the switch on more time and you unplug it. The light will come on steady and you leave it that way for more than 5 seconds. You then press the switch three consecutive times and very quickly. Basically, you plug it in and wait for the few seconds it takes to start charging (and flashing).

I followed the directions given by the first reviewer for this light in December of 2015, so that I could change the sequence from low, medium, and high to the reverse. The quality of the light makes this potential flaw irrelevant. I am not charging this light in my bedroom, and so I have no problem with this unusual feature. Several people have stated that this flashing is annoying because it would interfere with sleep. In fact, when I woke up, I found the light to be in the on mode, with no flashing. Like others have said, it flashes when it is charging. It was almost completely charged when I received it, but I plugged it into my USB laptop port and started to charge it. But, you don't have to press too too hard it is just enough so that the light does not come on while in your pocket.

As others have mentioned, you have to press a bit hard on the switch to turn it on and go through its three factory modes of low, medium, and high brightness. Yes, it definitely qualifies as a keychain. It's made of black plastic and quite light in weight. The actual LED opening is 3/8 inches or 1 cm. So, all together, it is about 2.5 by 1 and 3/8 inches long (6.2 by 3.4 cm long). The total length (it is tapered at the end where the LED light is) is about the length of a typical 5th finger in an adult 6 foot man. I received my Surefire Sidekick light and I am pleased with it.
