Since you posted this originally back in June and I replied mine was fine back then, mine has since that time broke as well. Not a crack in the same spot as yours, but mine cracked at the back of the vertical tube where the seam is at

I didn't bother with contacting them though, I just went on ebay and plunked down $10 for a new one rather than wait for a replacement. The replacement one does seem a bit more heavy duty than the original one at least so maybe it will last longer than 10 months this time.
