I'm a big Panasonic friend and the oil is determined also very good, but the price is unfortunately also very covered (311 euros per liter!). Therefore, I have not bought. I wrote for those who wish may purchase a good product, but also want to save a few euros this review. My recommendation is a "normal" mineral resin and acid-free precision mechanics oil / sewing machine oil. This is available in many supermarkets and hardware stores all in the 100ml bottle for about 1.50 to 3 euros. Or at Amazon, here is a link: Precision oil sewing machine oil Universal Oil 100 ml bottle or search for sewing machine oil. The important thing is that it has a low viscosity and resin and acid free. So please do not use vegetable oils, which gum up over time when in contact with oxygen from the air and the mechanism is stiff. I'm using the resin shown in the Link and acid-free sewing machine oil for years for my Grundig beard hair trimmer, a sewing machine, hinges, various cylinder locks and windows locks etc. Everything runs smoothly even after years and shows little to no wear. Who does not trust the quality and want to be sure, yet want to save 2/3, which I can also recommend the quite expensive but very good Ballistol Ballistol Universal Oil 50ml bottle Because I have to forgive star and the price per liter is extremely high, I forgive 3 stars to the product certainly good not too much to devalue, but at the same time to consider the price / performance ratio.
