okay my friend alyssa tried the orbit infusion set. she used it for 3 months. it stuck very well because of the heat activated tape. the best part is it comes with blue tubing try to avoid steel canula's because when the get ripped out they HURT. what worked well for alyssa was changing the site every 2-3 days. disconnecting for a bath or shower depends if you have a waterproof pump or not. No matter what infusion set you use I recommend you always prime until you see insulin come out before connecting.
another infusion set which is the most painless one I have ever tried is the inset 90 by Animas. it comes with an inserter built right in. For me it is the best. no matter what infusion set you use the max you can wear it is 3 days. I totally recommend you try the animas inset. it is very comfortable. it comes in many colors too.
let me know if this helps I really hope it does
