Hello, users of the 640G will be familiar with the clip that is not very clippy or robust. When I got my pump the rep told me the pump will last 4 years but the clip won't and sure enough 18 montths in my clip went all wonky. So I requested a replacement and they sent me not one but TWO, and it's a new design! The bit that goes inside your waistband is longer and it seems a lot more springy too. Seems a lot more secure so far!
Just thought I'd share in case anyone else has been having trouble!
