Battery compartment is not protected from water.
used with great results for a little over a year, Then it stopped working. Opened the battery compartment and discovered a foul mess of corrosion and black water. Cleaned it up and it worked a a couple of weeks. It now pumps water into the nose but the vacuum is not working so the device is useless. I will try the new model. Hopefully they have corrected their poor design.
