The VARON 1-6L Continuous Flow Portable…
The VARON 1-6L Continuous Flow Portable Oxygen Concentrator is great. The shipping of the unit was fast. The instruction manual was easy to follow and I am very pleased with the performance. My 4 instead of 5 is because I ordered a second battery that arrived over a month from the purchase date. Customer service was very responsive and kept advising me to have patience since the additional equipment was shipping from another location. My patience was rewarded by receiving the extra battery today.
