Hello JaneLo, thank you for your feedback. We have carefully checked our return samples and could not find any discrepancies. The capsules were inserted correctly and the coffee flow was perfect. As we are not aware of any similar complaints where capsules have burst - regardless of the variety - it is difficult for us to trace the exact problem without a photo. However, we suspect that it may be a specific problem with the machine, even if this does not occur with all capsules. If necessary, we recommend that you send the machine in for repair in accordance with the information provided by the distributor from whom the machine was purchased. If you have any further information or photos, please send them to us so that we can investigate the issue in more detail. Best regards, your M-Infoline team
