They are made from the plastic most other products come packaged in. Flimsy... you know the stuff you have to cut through to get something out of the package? These are made with that plastic. Also, annoying, these are not stand-alone testers. You have to use them in line with an existing circuit. They have no power built in, only a three pin input connector. I'm sure they have uses, and they do work. They're just not the tester you see on some videos where you just plug in a servo and test it. You get 4 of them, so, can't complain too much. Just not what I thought I was buying. No hookup instructions, but if you're buying these you probably already know.
