Oops! You are right to contact us. It goes without saying that your Dopper bottle should not have a production fault.
Please enter your address, the colour and version* of your Dopper bottle in the chat at the bottom right of your screen.. If at all possible we would very much appreciate a photograph of the fault.
*We have two different versions of the Dopper Original. The spare parts of these versions are not interchangeable. You can recognize the Dopper New School on the blue ring in the cup and the lower screw on the bottle. There's also a little drop on the bottom of the bottle.
On receipt of the form, we will contact you as soon as possible.
