I use this kit in my class. I teach electronics for slot machine technicians at casinos, worldwide. (slot-techs.com) It takes my students 2-3 hours to build it. It gives my students the opportunity to practice soldering on a high-quality, double-sided PCB, using precision, 1% tolerance resistors (5-band resistors), and a wide variety of discrete components. The goal of my class is for my students to know how to test discrete components so this unit is perfect. Of course, there are dozens of variations of this unit available. Some sell for thirty bucks! This unit works perfectly well, and includes a ZIF socket AND a case! The case is beautiful. Interestingly, some of my students have spontaneously opted to NOT remove the protective, brown paper film that protects the acrylic case and it actually looks really cool that way! I add three clip leads to the test points in order to test components that otherwise cannot fit into the ZIF sockets, such as when the leads are too short or bumpy with solder. We run the three wires out of the power jack hole in the case. IMHO, the power jack is superfluous and it would be just as good without it. The 9 Volt battery last just about as long as the shelf life! We only use it for seconds at a time in normal use. Anyway, I REALLY endorse this product. I buy them by the dozens. All arrive 100% OK in 4-6 weeks.
