Soda stream machine, 4 tanks, 3 reusable bottles Priced to sell, account for higher shipping, and tbh, I don't know 100% if the tanks are full - though according to my google search in the second to last pic, and the pics of each tank on my kitchen scale, they seem full (?). I know the tank without the white cap still has CO2 - I tried it yesterday and it carbonated the water. If nothing else, they should be exchangeable for a credit. The plastic bottles are clean but there is soda or something that collects in the base as shown in one of the pics - it's on the outside of where the liquid goes - it's just a bad design to try to clean. Cleaning out my cabinets!
