Do not shop here. This company does not honor their warranty and refuses to give refunds when they’re clearly in the wrong. It’s beyond frustrating, it’s disgusting. My father has been in and out of the hospital for the past 4 years, and instead of showing even an ounce of decency or compassion, this company chose to take advantage of the situation and rip him off for thousands of dollars. On top of that, they are completely deceitful, claiming their oxygen concentrators are “medical grade” when they are absolutely not. That kind of false advertising is dangerous, especially for people who genuinely rely on this equipment for their health. They don’t care about their customers, they don’t stand by their word, and they will screw you over if given the chance. This isn’t just bad business, it’s unethical and predatory. Avoid them at all costs.

Buyer beware! This company says they will accept returns unopened with full refund, not true.. they give you 60.00 bucks and then donate if you need or if you do want to return you are looking at very expensive shipping fees not worth returning.

We’re sorry to hear you feel this way. We always strive to offer fair and transparent service to all our customers. To clarify, our return policy doesn‘t promise a full refund for unopened items. When we spoke about your return, we were working with you in good faith to find a reasonable solution, as the product had no quality issues. We hope you can understand our position. We wish you all the best.

I wish I could give NEGATIVE stars. Absolutely horrendous company. Awful product, false advertising, abysmal customer service. STAY AWAY

The unit wasn't what I expected and in trying to get a hold of someone the phone # that came with the unit went to a full mail box and the email wasn't accurate email. I went on line and found a phone #. That person said I had to contact customer support via email. I requested via that email to receive a phone call and was advised communication only via email. Basically you have no support. Their response they would call. I tried every email sent me and never got a CBK after giving them all the info requested. Their response not true
Response from TTLIFEJan 4, 2026
Dear Customer, We’re truly sorry to hear about your experience, and we sincerely apologize for the frustration this has caused you. We do want to clarify that we do provide phone support when needed. Please reply to our support email and include your phone number, time zone, and a convenient time to call, and our team will be happy to arrange a call with you. Email communication is still necessary, as some support and warranty processes require written confirmation to ensure everything is handled clearly and correctly. That said, we absolutely understand the importance of speaking with a real person and are more than willing to do so. Your feedback is very important to us, and we’d truly appreciate the opportunity to assist you and make this right. Kind regards, Customer Support Team

I ordered because website said in stock and ready for shipping. They charged my credit card immediately. I was contacted the next day with a statement that the product was in fact not available and offered an alternative unit that was stated to be the same functionally but a few visual variances. The statement even stated that the alternative product was local and ready to ship. A USPS shipping label was created and that is about all that happened. USPS never recieved the product to ship it. The company responses are written very poorly and it is evident that this is not a legitimate company. My husband passed away this morning and I do not need the product since they could not hold up their end of the transaction, I have filed a dispute with my credit card to have my money refunded from this fraudulent company
