Sodastream (Calcot RG31)

Soda stream - works fine, has a partially filled canister in it.
The boxed canister I can’t remember if it’s new and full or used and empty - try it. If it’s empty, there’s a return policy that gets you money off the replacement so worth having either way.

NB - no bottles. The plastic ones expire after a time so they’ve been binned.
