Seems to work as expected and looks consistent in quality. The only problem I have with it, is the opening being too small for my hand when it is running low. I bought a another brand last time with the same quality and I could reach inside. I comfortably fit men's large size gloves, so my hands aren't huge. Maybe a long handle scoop would help...

No taste or texture - it completely dissolves!

Easy way to add fiber to diet. Stir it in coffee or a non-carbonated cold drink. You can't tell it as even added because it completely dissolves.
