@mtinderscott2626 Sorry not Sue but a fellow user/owner of eFlow for several years now. 7% 4mL saline nebulized in less than 5 minutes, with no noise. Nebology.com is an authorized reseller of this device, which by-the-way, has been used in the CF population for years. Tried and true introduced over a decade ago. I only wish they would reduce the price to make it more accessible to other patients. Nebology.com tends to run sales around holidays. The best discount I've seen is 40% off, which may have been around the December/January holidays. Usually 25%, sometimes 30% off retail price. Still pricey. Worth every penny as it's a giant time saver, especially since I neb 2x day, 365 days a year. However I can reduce time spent on managing BE, is worth it to me. Nuff said!

@mtinderscott2626 Nebology.com often has sales, currently it is priced at $899, but ight now they have a 20% coupon until the end of the month - net price $719.
It comes with 2 power heads (my partner & I each use one and share the base.) For us, the silent operation & speed are great, but the portability really sold us - we travel a lot, and between the small size, light weight and long battery life it makes our lives simple.
