not sure what you mean but i have combo this is the second one
i find the clip to the belt type as you can take pump off for manual use or leave for the blue tooth bolus
also i find that what side you fit the needle on when driveing wuth seat belt as this can be a problem
also at night clip can go on pjs
have tried cord round the neck gets in the way also a schoolboy on this site just tucks in a trouser pocket
in the sun i have adapeted a camera case that clips or go via a belt
good luck very very good machine but you have be a good operator to get the best out of the pump
vic 6 years on pump
