Great service! 

They shipped my new canisters as soon as I dropped them off at the PO, no waiting.  Soda Sense has saved me hundreds of dollars and hundreds of bottles into the trash over the last few years. Best decision ever!

We've been very happy with Soda Sense! 

Instead of looking for a store to swap out our empty cylinders, we simply mail them back. Once the return package of two has been scanned, a new one is on the way. Having a 3rd cylinder is great; you never run out of gas. The price is very reasonable, too. I've contacted consumer help a couple of times and they resolved my issue immediately. Again, we are pleased with Soda Sense and will continue to use them!!
