Coghlan's 4-in-1 Whistle
I got this whistle as a requirement for an outdoor safety course. It is really a whistle with a couple "fun" features on the side. The compass works but I am not always confident that it is really pointing north. The thermometer is a pleasant surprise and seems to be accurate (although knowing the temperature seems to make cold nights feel colder). My main complaint is with the magnifier. I like to use magnifiers as fire starters (what other use is there in the woods?) but this lens is not powerful enough to do so (a 5x is desired but I have no idea what power this one is). That said, this is a great little item for the price to throw in your pack.

4-1 tool Great Value for Price!
4 Tools in 1:
4) Magnifying Glass
This is a really good item for its cost of $2.97. I am not sure if it's the compass or the whistle that makes this tool great, but it has them both. The basic idea in survival, IF there will be a rescue, is STAY PUT. So you don't need a compass, but I am the kind of person that doesn't go out into the field without a compass. It is the basic directional finding equipment. This compass, although inexpensive, is dutifully accurate if you need it.
The whistle is a core signaling device. Next to the signal mirror, the whistle takes the least amount of energy to use and can be heard at great distances. Ask any rescue services person what is the most important signaling device for a person to carry and you will get the whistle.
In addition to the compass and the whistle, this handy little device also includes a thermometer and a magnifying glass. I like having the thermometer available, just because I like to know the temperature outside. The magnifying glass is good for finding splinters in your finger, but I don't have a lot of other uses for it. I, personally, have never been able to start a fire with one and I don't think this particular one is good enough for that anyway, but it comes free with the other stuff.
Good tool - buy it!

All the tools surprisingly work as they should
I found this whistle a very useful tool for my survival, hiking, or camping backpacks. At first looks good quality and all the tools surprisingly work as they should. Its noise can be heard from a considerable distance. I bought it since I needed a very small compass as a backup when geocaching and its accuracy impressed me. My only suggestion is to change the keychain for a nice carabiner.

Avergae, but to be expected
The only problem I have with it is teh thermometer only goes down to 0. Its not very accurate in weather below 30.
