Includes Sodaking carbonating machine in white, one 60L CO2 cylinder and a 1L bottle (free delivery with Prime).
copied from previous deal here
1L bottle is worth about $5, plus $25.90 for the CO2 cylinder and that makes the difference about $15 for the dispenser machine.
Previously paid ~$60 for the same components in a Sodastream kit, so a bit cheaper than that.
Biggest difference between this and Sodastream is you have to screw the bottle in to these. It's annoying but a minor thing.
