    It was difficult to turn the car key to start the car (it only did it in the heat, in summer), and I said, let me first try using contact spray (the barrel definitely had an issue). Now it turns like it did when I bought it 12 years ago! The spray did a very good job.

    I would not buy again. It did not do any special job that I can't do with much cheaper products.

    Expensive, but I was hoping it would be useful to me. I tried it on a remote control that had "died" and in the end it did not come back to life, I also tried it on a digital wristwatch that used to work but at some point stopped working, again it did not succeed in reviving it either.
    It probably helps somewhere, before I bought it I had seen good reviews, but in my case, I had two out of two failures.

    I have a Yamaha HiFi amplifier and lately whenever I adjusted the potentiometers, e.g. for bass - treble - Loudness etc., they turned very hard and the sound from the speakers had a "crackle-crunch"... other times one speaker would completely lose sound, etc...
    So I opened the case and put some of this (both inside and outside) on the potentiometers in the small holes and started moving them left and right 30 times... The difference is huge!!! Now they turn like "butter" and I have no strange "scratch" sounds and no distortion... and they work perfectly! It worked wonders!
