Hi Raney. I had a Pari Sport travel size nebulizer, but it died on me after 1 year of use. I have since bought a Vios green compressor and it has worked very well so far. Other members on here recommended it. I have found that certain neb cups wear out after only several uses. I think the last cup I bought was a Pari brand and is working well. My nebulizing time has been cut in half by using the new cups. I have been cleaning my cups by soaking them in heavy vinegar water and drip drying on a paper towel. I wonder if the heat in those bottle cleaners are distorting/warping the innards of the neb cups and that may be what is causing them t malfunction. I used to use boiled water to soak my cups, if the water was still too warm, it ruined the cups.
