These things frequently leak even when new, and the rubber seal falls out and is difficult to get it located back in the groove. They give them free with an order, but I end up throwing them away after a few usages because they are more trouble than they are worth.
I still have a different style shaker bottle that i got from this site about a year ago, and it is still going strong through the dozen or so of these that i have thrown away. I wish they wouid go back to selling or giving away the older style. |
