Thanks for the welcome ... this is the best forum I've seen on the internet. The weather here in the south is rain and rain. Excuse my ignorance on the subject ... so far I've had a good experience with UFO's products and after-sales relationship with Jon Cornel. Certainly if I had read this forum before would not have made any kind of insurance business with Jon ... I even delete your site from my computer ... but that's not the case ... I reiterate their products are good, ... that sounds very hard !!!.. can be ... but some people like it. Performance on the dynamometer is higher than some brands that have already been mentioned here ... I would not mention them. Finally, I've never talked to Jon, I do not know, I do not speak English and I had to delegate this to friends and google translator .... as in this case. Thanks again for the welcome and congratulate you for the excellent forum .... undoubtedly the best and most complete of the internet
