I’m wondering about your experience with them:
- Have they replaced your seltzer/soda buying?
- How much do you use your equipment?
- Where do you get your CO_2 refilled and how much does it cost?
- What flavorings do you use and which are your favorite?
- What equipment did you buy and do you recommend it?
You could also check with some grow shops. Some… Some specific kinds of grow shops sell and swap CO2 tanks.
