| No flow regulations, it will give you what your lungs have capacity to inhale without "working" for it. Feels easy to fill up lungs. The hose is just "snapped" into the "thingy". |
 |
| Filters, changed every week or so. My throat hasn`t been sore since i started using this. |
 |
| No flow before you inhale or push this test button. Will also stop when you stop inhaling. |
 |
| No waiting for the bag to fill up. For me everything else than this is useless. Everyone should have this!! |
