I contacted them on the 21st of October regarding issues with the 8mm sets, told me they would get their technical department to look into the problem but I've heard nothing, seriously considering switching back to mdi as the sets only seem to work in a couple of sites and I asked them if the 10mm or the steel cannulas would be better, but as I said, no reply.
You should report every set issue to MHRA website.
I would have done but got told the problems were withe being lean and muscly and not fat for cannulas to work constantly. I was told to replace the 6mm rapid d's daily initially. Plastic ones have never been good in me due to them blocking so easily.
You really should phone accuchek back and speak to their pump care team. There should not be issues with sets.
Are you 100% that there is no way the causation can be foods, bolus's basal rates, timing setings etc. i knew 100% as I only ate at 6pm each day. So when one day basal and readings were good and the next went horrendous they know with me that it is not any incorrect configurations. Then even with daily changes -my worst day was 5 changes in one day.... Then the next day perfect... It was all blamed upon me being to lean.
Honest, if you are getting any failures where you can guarantee its the equipment then the only way is to report to MHRA and also email Accuchek as well.
