I’ve just bought a trolley for my Inogen G5 and I can honestly say it has been life changing. Carrying the poc has become impossible for me and I haven’t been able to find a cheap alternative trolley that is secure enough. After advice from Lee I purchased this trolley designed for this poc and it is excellent. I have just spent a weeks holiday in Liverpool where I’ve put the trolley to the test. The big wheels make it run very smoothly and the poc is secure. It also feels very light. So I can carry the charging lead I have bought a small handbag that sits neatly on top of the concentrator. Thank you for supplying this great product that arrived so quickly and to Lee for the customer support helping me make the decision to buy it.
