The bag itself is really noisy plastic, not like soft plastic without noise, which is very inconvenient because I don't want to wake my family when I work late or something else, which is a minus For me. I don't think the plastic grinder is accurate compared to the same grinder in my previous bags purchased from Costco. Another disadvantage is that the bottom of the pouch does not open fully, when trying to open the pouch for use only a quarter of the bottom opens which is inconvenient for some applications. The price is about 3 out of 5. because of the above issues. I paid $29.99 + tax.
