I like the t-slim. it now integrates with Dexcom, but I have the earlier model. you can put a temp basal rate in to last four days and you can program in different profiles for basal rates and ratios. there is a connector for the tubing just outside the pump that can be irritating and their clips aren't the best. I think they're working on improving those things. one thing that bothers me is that the representative told me if be able to trade in for the model with the CGM when it came out. then when it did, they wouldn't let me. it's similar to something Medtronic did, so basically I think you just can't trust representatives on these things. if something like that matters, get it in writing.
