It works perfectly
This pump works much better than expected.  I don't need this medically, but the added width created by this device is excellent.  With the red and black seals, I recommend placing them first in oneself and then placing the tube, since even with lubrication they may be tight (which is desirable for greater suction).  It can work without a seal but it works best with one.  The lower setting creates a large amount of suction, so it only progresses to greater suction when ready.  Use it as instructed or recommended by your doctor.<br /><br />  Cons:<br />  - Be sure to open the "mouth" accessory first and wash it thoroughly, as it is covered with dust that adheres to everything.<br />  - The motor section is not waterproof.<br />  - The frame is larger than expected (which is also a professional because the device can accommodate many input sizes)
