THIS IS THE BEST FLAT IRON OUT THERE. I HAVE HAD MY FOR 4 YEARS NOW, STILL WORKS AS GOOD AS THE FIRST DAY I BOUGHT IT. IT WORKS GREAT WITH OR WITHOUT PRODUCT. GLIDES RIGHT THROUGH THE HAIR AND LEAVES IT SILKY STRAIGHT. DON’T WASTE YOUR MONEY ON A CHEAP FLAT IRON, THIS IRON IS WORTH EVERY PENNY. I GIVE THIS FLAT IRON 5 STARS
