I bought one of these B-Stock for my daughter, who is learning flute. Unfortunately, it came with a faulty G key. Thomann promptly sent me a replacement, which had a faulty F key. This again was replaced, and the final instrument is genuinely an exceptionally good-sounding flute! It comes with a rock-hard carry-case, which also contains a cleaning rod, polishing cloth, and the gooey stuff for lubricating the joints (my daughter's teacher advises against using the gooey stuff, as it tends to make the flute gooey!).
Apart from the initial problems, which were dealt with in a professional manner, this is an excellent instrument, unbeatable value for money!
