This stuff actually works. Breaks through corossion in electrical contacts, and prevents corrosion from forming. Wonderful. Worth the price.

Everything worked as is, I had no problem with this product, and the smell is really nice

I've been using this product for over 10 years now and I can say that it does everything that they claim. I use this mostly for automotive use like the battery, ground connections, and anything that can cause corrosion in the electrical systems, I use this. I also use it doing electronic repairs like switches and potentiometers. It not only cleans the contacts but prevents future corrosion from happening. Like any product you will have to re-use the cleaner/ corrosion blocker if the environment is open like in a car but a can will last you about a year if used the way intended and reapplication is also dependent on how open your environment is. For cars I'd recommend every 3months and electronic equipment used in a household environment I'd reapply every 6 months to make sure you get no corrosion on your devises. 5 star rating all the way. I've never seen such a good product. Again, I use this all the time, and have been for over 10 years with exceptional results.
