    My experience with O2 Relief - Oxygen Concentrators in Irvine has been incredibly frustrating. It's…read morebeen almost two weeks, and we've made absolutely no progress. Our doctor's office referred us to this location and told us everything should be straightforward and that we'd be good to go. Unfortunately, that has not been the case at all. Instead of helping move things forward, O2 Relief keeps pointing the finger back at the doctor's office. Meanwhile, we're stuck in the middle with no clear answers and no sense of urgency. When you're dealing with medical equipment, delays and lack of communication are simply unacceptable. Customer service from has been extremely disappointing. We haven't felt supported, informed, or prioritized at any point during this process. Overall, this has been a stressful and frustrating experience. Based on our experience, I would not recommend this place to anyone.

    I was sent home from the hospital requiring 24/7 oxygen. The vendor the hospital contracted was…read morehorrible. They were late on delivery, no communication and difficult to reorder my needed oxygen tanks. Thankfully, my cancer-coordinator helped me get a referral to replace them with O2 Relief! From the first email to our in-person visit to their showroom near HMart in Irvine, Issa was professional, prompt and patience to explain the many features of both in-home and portable oxygen concentrator units. All covered by Medicare, and he took of all the paperwork to transfer away from the previous vendor. Yes, I highly recommend to Issa and his team at O2 Relief.
