HI, I've written a lot about the Pari eRapid and have owned it for a couple of years. Bottom line it's quick, quiet and reliable. It's been used for years in the CF world. Pricey but glad I $plurged and have zero regrets. PARI says that the handset needs to be replaced every 6 months but I go much longer than that. The biggest drawback is that it leaves behind about 1 mL of saline. Keep in mind if you take it traveling, it still needs to be cleaned (soaked in soapy water) and steamed or boiled for sterilization. Not microwave safe. I boil mine in a ramen pot and let it air dry when I travel by plane. Traveling by car, I take the Grownsy baby bottle steamer with me without the tank so it takes up let room.

Here's a link to some of the things I've written.

PS - I purchased it from Nebology during an extra discount time. They recently ran an extra discount over Independence Day weekend. Look for another during the next holiday period.
