At the moment I can not use the cartridges as my own is not switching on. Frank is aware and will continue to help out next week.
However I am unable to find the supposed ‘new’ app and unable to register and connect my device.

So right now the device, cartridges and mesoglide are completely useless.

I love the product. But a whole week for delivery is poor. With ivanmed 2 days max sometimes just 1.
I know it's new for UK but hope it gets better.
