Review: Bought for whistle and thermometer, compass is a plus. - 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 and use your nails to grasp it and swing it open from the other side. Or use a thin tool like a knife or small tool to push it all the way through. Usefulness: it's a little magnifier, it magnifies things a little. Other: The clasp itself is all plastic, no hinges. To open it wide enough to hang, you give it a push and it bends in somewhat. On it's own the clasp sits slightly ajar (1mm). It can attach to anything thicker than a millimeter and not fall out. I was going to give this four stars because the compass MAY be off by a dash, BUT that may be my lack of skill so in all fairness I won't take off a star. Also even if it IS off by a dash, I am backpacking trails so I don't need anything heavy duty, and if I did I would buy a compass on it's own. This little item is amazing! I bought it primarily for the whistle and thermometer and it meets my expectations. The compass is a plus and I don't care squat for the magnifier either way. The clasp is a simple plastic thing, it's thick, sturdy and will do it's job, I don't see that breaking anytime soon, It can also be replace by a tiny carabiner if you prefer. All in all 100% worth the money.
Review: Cheap but effective - This clips on nicely to my backpack for when I travel. I like knowing the temperature when I am hiking and it is convenient for the direction as well. I haven't had to use the whistle yet.

### ⭐⭐⭐⭐ Buy it, you will not regret it
*by W***W on June 10, 2016*

I purchased this about 4 years ago and have been meaning to get more of them for my other backpacks. They are good quality and I don't think you will be sorry your bought one. Each family member should have one if you hunt or hike or like to walk in the woods. I just purchased 2 more just recently. I always have one on me when I go hunting or walking in the woods. The whistle is very loud and would think it will carry a good distance. The compass works extremely well, having used it a few time when I got turned around in the woods while hunting and always made it back to my Jeep. I find the Thermometer has come in handy while hunting many times. It appears to be quite accurate. I tested once with another thermometer and they both had the same reading. Haven't used the magnifier so can't comment on it. The clip is sturdy and hasn't broken even with heavy use. I am constantly moving if from my hunting vest to other things. That is why I bought additional ones so I don't have to remove it. These are great for the price and are nice gifts for your friends if they share your outdoor activities.
