I'm a absolute novice and bought this alongside an RS3M 2020 as my entry into cubing as felt I wanted to get the best out of my cube. I'm very happy with the product, it feels fast and light and is not sticky or messy, even when I popped a piece out of my cube whilst setting it up it didn't make a mess. I did tend to have to use more than a 'few' drops in order to feel a benefit but that was with a brand new, completely dry cube. Good product and great service from Kewbz.
