Expensive but will last a long time.
I find that this works well. People say that you can just use auto window cleaner but I've not tried this. This Trend fluid is very expensive but I find that I only need a few drops each time that I sharpen so the bottle should last a long time! I've taken 1 point off because of the excessive cost.

Works as advertised, I.e. does what it’s intended to do.

I can't believe I spent what I did on some liquid in a bottle. That said, it does what it claims and makes sharpening quicker, easier and doesn't have the same effect as water can with causing rust on your expensive diamond plates from letting metal sit a little too long. You don't need much at all, just a spray or two is good enough on a fine stone. What I received is not like in the photo though, I got it with a spray top rather than a pop top lid. I hope it results in using less, just don't waste it with overspray that doesn't end up on the bench rather than the stone.

Excelente fórmula, lo recibí y lo utilicé de inmediato, estoy gratamente satisfecho, el producto funciona tal como se anuncia, desbloquea las lápidas y evita el depósito de limadura, su fluidez es precisa y evita que el instrumental que se afila patine sobre la superficie, además no genera residuos excesivamente grasos, es fácil de limpiar. Mejora otros líquidos para afilar que utilizaba. Un producto así se agradece en verdad.

I resisted buying this “fancy” oil for my diamond stones because of the price but it’s totally worth it. It cleaned up some of my clogged fine grit stones when nothing else has, and works better than other oils I’ve tried. I put it in a smaller squeeze bottle so it doesn’t come gushing out and waste.

I first saw this product being used by James Hamilton at Stumpy Nubs and it is fantastic. The down side of it was the first bottle I got only had the cap on it that is used to drip the liquid on to the diamond stone and it leaked so I lost a lot of the liquid. The second bottle had a top that sealed and a second top for applying the liquid to the stone. I am very happy with the product
