Sorry that you were not happy with your Coffee Joulies. We aim for 100% satisfaction with our customers. This means, if you are not happy with them, we try to do everything we can to make it right. The return information is below but first here are a couple of common things that may help.
If you want to extend the amount of time a drink stays hot:
For this you may need to improve the mug that you are using. If you compare any two identical mugs, one with Joulies and one without, they will reach a tepid temperature (~110f) after an equal length of time. The mugs insulating properties determines that length of time. For a open ceramic mug it might be 30 minutes, for a vacuum insulated travel mug, it can be over 5 hours.
If Joulies are put into any mug with a beverage above 165f, the beverage will get to a safe drinking temperature faster, and then stay in the comfortable range for longer, before it gets cold.
If you are not satisfied for any reason, you may mail them to:
