If you want to get some sound out of your project but have a tight space budget, this is a good way to do it. This 0.25W, 8Ohm speaker is only 40mm in diameter and just over 4mm thick, the same kind you might find in one of those "talking greeting cards".
The wires are thin and you have to be careful about handling it with the thin speakers. I recommend adding hot glue or electrical tape to reinforce the connection. I actually soldered thicker gauge wires to the speakers and it works better. =)
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

I used this combined with the Sparkfun BOB-11044 mono audio amp breakout to add a horn to my son's pinewood derby car. Thanks to this, his car took the top trophies for "Best Design" and "Most Unique"!
EDIT: Somehow I accidentally gave this 4 stars when I meant to give it 5. It seems I can't edit that part of the review. Sorry. @Sparkfun, feel free to correct and remove this edit note.

First the speaker does actually work, all you need to do is plug it into a function gen and i set mine to about 3.5 Vpp and it worked great. That being said the choice of wire is pretty bad. The wire is stranded and it feels like after just a small amount of use that the wire is close to breaking off of the speaker, also its very difficult to plug the male leads of the wire into a breadboard, I was able to get it to plug into female header connectors but they dont stay without you hold them. All in all I would probably recommend another more robust speaker, or atleast different connecting wires. UPDATE: Just after writing this review, having had only used the speaker for about 30 minutes one of the leads has broken off of the speaker.
Sorry to hear your units has broken. With these being only $1, there are some quality limitations. Contact us at Tech Support @ Sparkfun.com and we'll be happy to credit you for the broken speaker.
These are nice little piezo speakers and great for student use (e.g. photoresistor Theramin). They run directly off an Uno output, keeping introductory wiring simple. The wires are too fine to attach directly, so we pin them into the headers using short lengths of 22 ga solid wire. As mentioned, the speaker wire solder joints are fragile and my students either tape the wires down or put a drop of hot glue on each one.
It's a pretty good speaker (knowing that it costs only 0.90 €) but its flaw are the two cables. They are litterally the weakest piece of electronic I've ever seen. When I connected it to my breadboard, the two cables immediato bent, unable to support the weight of the speaker, also because their ends are too short to completely fit inside the holes of a breadboard. I tried removing some of the plastic around the cable so that it could connect better. At first it worked more or less fine, but when I deattached it from the circuit, one of the cables decided to remain in the breadboard, completely broke. Knowing that the other one was gonna have the same fate, I had to cut it and to solder a pair of way more robust and reliable cables It wasn't a real problem, but it was surely annoying
