DeclanDeclan: This is a nice small little compass/whistle/magnifying glass/thermometer. Seems accurate and is perfect for just throwing in a bag to have if you need one of its functions. Build wise it’s plastic and the clip doesn’t seem very strong but for the money you can’t expect much better. It’s cheap and useful so I ended up buying 3, one for each member of my family. 4 stars seems a little harsh since it is value for money but because of the plastic build I can’t give it 5.

Alex Key: thermometer requires 10 minutes or more to read temperature in water so if you use it for swimming in cold season, you may have too long wait until you get a correct reading

JassuJassu: Y The thermometer seems to work fine (see pic), but I don't know how accurate it is.
N The clipper does not seem durable or reliable. I will replace mine with a lace/cord.
Y The magnifier was surprisingly good, I could see my dry skin up close lol.
N The whistle was not loud at all. My scream would be louder.
Y The compass seems to work as well (I compared with my phone's compass). It will point you to the
approximate right direction (example: North), but be careful to do this without any metallic objects around.
Also it will only work if laid horizontally on an flat surface. If you're holding it vertically, it will NOT show you
a correct reading.

Was it worth it?
For less than $5, yes!! Overall, the main functions worked as intended. The clipper you can easily replace, and the whistle, well, you can just buy an actual whistle for something really loud.

If you're looking for accuracy and long-term reliability, this might not be the gadget for you.
If you're looking for something small, compact and neat to have around in a go-bag, go for it!

AmazonAmazon: Whistle: Very loud. At first I was blowing on it too lightly and thought it was defective. I gave it a nice blow and wowza, yes it works great! Short bursts work well too.

Compass: I'm completely new at using a compass but I do know west has to stay west and so forth. I've tried it many times in my house, I shook it hard many times and checked if the directions still pointed in the appropriate direction. It did for the most part, although it seems to be off by about a dash sometimes, but that could be me I guess.

Thermometer: The print is small but my eyes for close-up objects is perfect so I have no problem reading this. For those of you who are far sighted, it may be a bit harder. I have no other thermometer to compare accuracy perfectly, but using my own bodies thermometer, it seems on point. When I turn off the AC in the house the temperature on this baby slowly increases and vice versa. The numbers that shown are by 10 values and the marked dashes in between are by 5 point values, plus an extra red dash for the 32 degree Fahrenheit.

Magnifier: Its takes a tiny bit of effort to pull it out, but you can definitely do it no problem. Push it in from one end...

nate: Some of the functions on this whistle are more novelties than essentials.

The thermometer is interesting to have, but I don;t know what use it really serves if you're already outside, and if the whistle is carried near your body, the temperature reading is probably not accurately reading air temp. anyway.

The flip out magnifying glass and signal mirror are nice ideas, but both are very small. I don't know if the magnifying glass would focus enough light to be useful as a fire starter, and the mirror may not reflect enough light to be noticeable from a long way off.

The compass is practical, but, like other tiny compasses, you might need to tap it a bit before it settles and points accurately.

The whistle seems to work well. Coghlan's doesn't provide any information on how many decibels loud it is, but it seems loud to me.

I would not use the LED light as a primary source of light while out hiking or camping, but if needed, it is bright enough to light the ground in front of you as you walk or to find things in a pack or get situated in a tent at night. The light stays on only while you hold the button down, so it won't accidentally get bumped on...
