Hello
@Eylise I use the 640g and think it’s a great pump, choose your cannula set carefully though, I started on the mio sets but had issues with inserting them and rashes from the set itself as it’s plastic, I then switched to the sure t sets which are manually inserted and they have been excellent.
Pumps are brilliant for tiny adjustments so tweaking your ratios and micro managing your control is good, also for turning your basal down for exercise. Have had a couple of cracked pumps which have been replaced within 1 day so keeping a backup of pens is vital. I keep mine in a pump belt 24/7 and that’s been great for me.
Good luck and let us know how you get on ?
