Review on 🔒 Tightvac 3 to 12 Oz Vacuum Sealed Storage Container: Keep Your Food Fresh with a 1.3-Liter/1.1-Quart, Black Container by Alexander Roberson

I bought 7 of these containers in 3 sizes. One of the first did not write poetry at all, and Revane replaced him. Based on the overall good reviews, I bought a few more to store ground coffee. I order roasted beans to order and it sometimes takes a month for them to be roasted and shipped to me. So I didn't bother using this container and the last 2 six ounce containers I bought about 40 days after I bought them. This container and one of the six ounces are unsealed, but both are past the 30-day return policy. The end result, 4 of the 7 I bought really worked. Revain replaced one under warranty and left me with 2 out of 7 not working. So bad I will never buy them again.
