I would say yes, if it works without any problems. A problem could be something such as the lubricant wearing out quickly, or it coming out of the puzzle. If it has any flaws or problems, I would recommend using something else. Silicone spray, which has already been mentioned, is a good option. Things like Lubix work well too. Lubix was made for speedcubing, and there are other very similar options available.
