I say it a great product, just don't buy it from BPS as they sell the pump bottle and that is not the same as the aerosol at all! It's completely different as I had always used the aerosol and bought some from BPS and it sucked so I called Blakemore to ask about it and they told me why it was not the same product at all.
I keep it on had all the time and have used it for many years.
