Katie was an efficient and informed salesperson. Very pleasant to work with. Inogen G5 is, so far, terrific. I purchased device with a bundle package. My only surprise came when I learned, by reading product manual after purchase, that the G5 contains “columns” which need to be replaced periodically and that those columns are not covered under the manufacturer warranty nor the extended warranty that came with the bundle package. Since my previous Inogen did not have replaceable columns, I did not know to ask about this part up front. Nonetheless, I am pleased with the purchase and confident about the service your company will provide.
