Described as a spring force extractor for integrated circuits. No, that is not so. There is no spring anywhere on this device. I'm sure I can handle it, but that's not really the point. I was tempted to buy this with the wrong description and I bought what I didn't get. If I had known it wasn't a spring device I would have bought a different one. Even if it looks identical, it is not the advertised brand or model. I will return it to Revane.
