Beautiful pattern and lovely cotton material , super easy to place over GCM . Only issue that it started to lift on the eighth day and was gone by the tenth . I will check full instructions again as it really lovely and I’ll try again 👍
The insulin pump belt solved a problem I was having with the clips always breaking.
Hi Ken, we're so glad to hear the belt worked well for you! Thanks for your support and positive feedback.
This patch is easy to apply. My sensor is more securely fixed to my arm with this patch and it remains quite dry after showering. Importantly it is easy to remove.

Thanks for the positive review Michelle! Glad that we could assist.
They could have used better velcro. This sticks to the fabric and tears it up. Otherwise works as intended
