purchased the G5 for RV
I retired in 2019 and purchased the G5 unit with two extended life batteries a few days ago for my wife who has COPD, although she doesn't use Oxygen regularly I needed a good reliable unit to keep in our motorhome when we are traveling. The business development rep , Ricky K. was outstanding and we received the unit three days earlier than expected, I would rate the entire experience as a 5 out of 5
