There are some downsides to using BSB's.
*Averaging the quality of the items put in is not always a good thing, such as when high quality materials are required for improving.
*5% of each of the stored items are lost every 30 days. This loss does not apply to containers on a deed with more than 30 days of upkeep left.
*Any [[enchant]]s, renames, and other "special" characteristics on items put in are lost.
