Great products and a great customer experience, even during this darn pandemic. You can buy online, but if you are able to visit, you will learn a lot more by discussing products and usage in person. Also great to be able to fit the mask before purchasing if you are picking one of those up.
I love how the Pulse Demand systems are like a robotic co-pilot; always making sure the passengers and pilot don’t become hypoxic while saving as much Oxygen as possible.
