i like them. They have great customer support. I don't own an Ofna anymore, but my neighbor has the Hyper 9 1.0 and it's a great car. Kept bending front right drive shafts and Ofna just kept replacing them. Finally sent him some upgraded versions for free and haven't had a problem since. I don't think their products are up to par with some of the bigger name brand companies, but damn close and very affordable
