Awesome product

I bought 3a and 4a from them, used them to dry solvents, leave in and store, and remove water from reactions. They work great. If I ever run out of them or find I need more than 7lbs in rotation I'd absolutely order more.

Size reference needs improvement

For first time users, it will be best if they had scales shown next to the item. Picture and unit described it's hard for new users to understand how big the unit is. If item has been poured out of the container and placed next to a ruler, it will help the buyer understand better the size of these pellets.

Perfect of a damp car

This product sucks up the humidity in my car aggressively and reduced the damp, musty smell to almost non-existent... I wish I had found them sooner but glad I did and it works. Probably good for gun safes in a basement too.
