Oops! You are right to contact us. It goes without saying that the bottom half of your Dopper should not have a production fault.
Please enter your address, the colour and version* of your Dopper in the contact form. 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 within a few hours.
Thanks in advance!
