I got one for DH too and although we love it we just get out of the habit and we have been drinking heaps of DC but it is definitely cheaper hun but you have to work it out and depends how fizzy you like your water too!!! We use it more in summertime actually and for around $60 I think they are great! It's good if you have a space for it on your bench too - that is our issue - it's charged and ready to go but sitting under the sink right now. I keep the bottles in the fridge and add cordial as needed.
