First few tries were fine then the number 2 roller got stuck. It sort of jumped off its axle! This does not come apart for cleaning so a few taps on the side got it back in the groove. Quite expensive but then so was the £50 Taylors Eye witness knife. Sadly I had already ordered a second one of these for my daughter when this one failed, so for me this makes the pair of these very Expensive. There are plenty of other roller types with ceramic wheels but this suction cup is very good.
TAYLORS KNIVES ARE REALLY GOOD THEY HOLD THEIR EDGE AND ARE REALLY WELL BALLANCED AND GOOD IN THE HAND. THEY ARE MORE PRECISE THAN CHEAPER KNIVES AND ARE WORTH EVERY PENNY
