Hello Phyllis,
Please excuse the problem with the device. All products that you buy from us come with a worldwide two-year guarantee. In your case, the device must be exchanged (we know the problem with the plunger that is not properly fixed). The exchange is free of charge. If you don't like the device, you have a 30-day right of withdrawal and can send the device back. In your case (because the device is defective), the return shipment is free of charge.
With this pitter, it is important to know that you can only pit normal-sized plums (length approx. 3 – 4 cm / 1.2” – 1.6”). The plums must not be too big, but also not too small.
Greetings from Germany
