Jon Sharp wrote a review of Vittoria EVO Tube on June 6, 2009
These tubes are super light. I could really tell a difference with them mounted in my tires as compared to some heavier tubes. However, I could also tell a difference in durability. I bought 4 of these and I've had almost 3 flats in each. I didn't think a tube would make a difference, but these were very prone to flats (mostly puncture). Great for race day, but not worth the hassle for everyday rides.
