I love mine. 700 x 23C Serfas SECA RS Road. very rarely flats. I'm at about 4000miles for the front tire and cannot remember changing a flat on the front tire. I've had to replace the rear, but only because I managed to ride over something which slashed the tire. I've had a few flats on the back, but not too many.

it's also pretty cheap. I get them at my expensive bike shop for under 25$.
