Very good investment
I would recommend the In oven to those that need oxygen daily. The system is very convenient and easy to carry. My only problem is that the battery becomes very HOT. Venting it still has the battery heating up. I, also, found that the 5 hour battery is not true to the hours. After a "full" charge I only receive 3hrs 45 mins. Poor advertising!! I'm fine with the system beats carrying an oxygen canister.
