As a small, super bright carry-light, the Streamlight ProTac 1AA Tactical Light is great. One firm press on the tail switch is all it takes. However, the strobe and low output settings are achieved by pressing the switch button twice or three times within split-second time limits, without doing it so hard as to latch it "on", or too lightly while working against a firm switch spring. It is difficult to do and usually takes me several tries to get it to set to strobe or low light. If those alternate settings are very important to you, I recommend stepping up to another model that has a separate selector switch.
The case has a velcro belt loop which can be used to attach it to anything small enough for it to encircle, like a wheelchair, a backpack, a purse, etc. It's a nice feature, along with the pocket clip. And who doesn't keep AA alkaline batteries available?
The AA battery, compact size, high output, rugged construction and price were major decision points for me to purchase this light. I would have rated it as all 5-stars except for the switch setting difficulty described above.
Pros: Very small yet very bright, and uses only 1-AA battery
Cons: Alternate switch settings very difficult to set,
