Correctly suspecting that Sirius Black sent it, Hermione Granger reported it to Professor McGonagall.

Once the fastest broomstick, the Firebolt was used by the Irish Quidditch team in the 1994 World Cup. He received a Firebolt as an anonymous present from his godfather, Sirius Black at Christmas 1993, after his Nimbus 2000 was destroyed by the Whomping Willow during a Quidditch match against Hufflepuff team.The Harry Potter movies never explained how Sirius, who had the Wizarding authorities after him after escaping from Azkaban, was able to purchase the Firebolt without being caught. Harry Potter is given a few different ones and they help him on his journey to understand himself and magic better. The bottom line is that Hermione was in the right to intervene in the Firebolt situation because in some cases "mind your own business" has to take a backseat to "better safe than sorry. Be the envy of all Quidditch players and Harry Potter fans and collectors with this authentic reproduction Nimbus 2001 broomstick.

A skillful and innovative broom designer, Randolph was the first to use goblin-made ironwork (including footrests, stand and twig bands), the secrets of which are not fully understood, but which seem to give the Firebolt additional stability and power in adverse weather conditions and a special non-slip foot grip that is of particular advantage to Quidditch players. This officially licensed Firebolt broomstick replica bares an astounding resemblance to the Firebolt used in the Harry Potter films. A miniature replica of Professor Dumbledore’s loyal phoenix, this Fawkes stands on a golden perch and has sparkling black crystal eyes that contrast with his bright red plumage. It continued to be made in relatively small quantities, partly because the goblin workers involved in the patented ironwork were prone to strikes and walkouts at the smallest provocation. One possibility is that it may be used as a foot-rest when one is on the broom; this was shown in many occasions in the films where the characters half stand on the bipods and also rest their feet on them.Given her suspicions and given that those suspicions were reasonable given what they knew at the time and given that caution should be taken with anonymous gifts anyway, Hermione was right to intervene in this instance. The Firebolt was capable of going from nought to one hundred and fifty miles per hour in ten seconds.
