The AeroGarden is less expensive on the AeroGarden site than on Amazon. Also, if you sign up for emails, AeroGarden offers a $50 discount on the Bounty Elite model and other coupons. In adition, AeroGarden often offers discounts on holidays. However, while the AeroGarden Reservoir (AeroVoir) costs about $40 on the two sites, comments on Amazon are extremely helpful. Some customer comments are copied below.

AeroGarden says that water needs to be added every 2 weeks, but that it's a go good idea to keep the water topped off. However, comments on Amazon report that you may need to water more than once a week when your plants grow large. AeroGarden says that the AeroVoir holds 1 gallon and provides an additional 2 weeks of water.

Note: The video further below and comments on Amazon indicate that since the AeroVoir works by gravity, it may require a stand when used with AeroGarden models that grow 6 or more plants. The 8" high stand shown below is recommended by Amazon reviewer Don Tony -- EXCEPT when growing strawberries! [See his revised comments with stand below.]

 Several Amazon reviewers report that after a week, algae will start to grow in the AeroVoir and discuss ways to handle that. One reviewer warns: "Can be very difficult to clean if you get mold inside of the AeroVoir or the tubing."
