That is a good question. When I started pumping they automatically suggested animas insets as the easiest but Tandem makes a similar one. Then I switched to contact detach and also they sent the animas one. I even asked why cant I get a Tandem one and they said it didnt matter. I wanted the Tandem one just for that reason to support my company. So not quite sure why people tend to move towards other companies for infusion sets.
