With one exception all pumps do pretty much the same thing and event he one that is different does pretty much the same thing, just in a different way.
Also, most pumps are about as reliable and functional as another. The main drivers are what is available, and what can be afforded. As mentioned above, pumps are delivery tools. They are great tools, I love mine, but they are not for everybody.
Since you mentioned Medtronic, I found their contact information for the Philippines.
