Shipping and packaging good & fast! The cartridges are relatively expensive ..... but they are really good! Any other attempt to make do with other garbage bags does not pass the "smell test" ....! Honestly! I do not know how ANGELCARE makes it ... but these cartridges bags do not smell and Scots the outside world extremely well from the smell of the "little magic works" of offspring from. Conclusion: Expensive but good ... and so recommended! One star deduction only for the relatively high price.
