Karol, I haven’t experienced the tubing crimp (yet), and falling off is the opposite of the problems I have. There are times when I have to fight the clip to get it off my waistband (jeans or leggings). The weight of it also drags down several dress pants. I do miss my Animas pump, it had flaws to be sure, but less flaws than my 670g. Since I was a transfer when Animas closed down, my warranty will be up this September I believe. I may look into the Tslim myself.
