The Doinkers and Sims are great products, but I found that the Octane can match them inch for inch, is cost effective and looks great. The fact that Octane can make such a quality product that can match the bigger names that have been around much longer says a lot about the company. All I am saying is that you cannot rule them out until you try them. You'll know what you like, and it might not be Octane, which is fine. Buy what you think is best.
