We're sorry to hear the remote isn't working. The remote uses a CR2025 battery. If it still doesn't work after installing a new battery, please contact our support team at: [email protected] We will help you resolve this right away. Thank you for your understanding.
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.

I think the machine is well designed and I am finding it useful. My only complaint is the type and level of sound. I can probably adapt but, currently the vibration sound and the pulsing sound make it difficult to read in bed.

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

Hopefully the unit is putting out the correct amount of oxygen as stated. As far as shipment and the company, they were great. Quick shipping and fast delivery.
