| I've been pumping for over 7 years now. I started out with the MM 508 and was using the sof serters which were ok but I don't like the extra tubing hanging off the site. I now use a MM 715 and use quik sets and I've got to say I've never had a problem with them. Yes they sting when inserting from time to time but I've never had bent tubing and I've never had scar tissue build up and I always insert in my stomach. I guess I'm one of the lucky ones.
My son however uses the silhouettes and he doesn't mind it anymore but it is intimidating by the size of the needle. I insert his manually. We did try the Sure-T's as well but they were always coming out. Since using the Silhouettes we haven't had any prematurely come out.
It's probably individual preference. Try different ones and stick with the one that works best for you. Everyone is different. |
