pleased with my battery

the only thing missing is a type of desktop charger. so i can charge my backup while using my basic battery. and a carrying case, the cardboard box will deteriorate soon.

Rythem P2 Recharable Battery

Battery was shipped and received in a timely manner. The only complaint I have is the cost of the battery.

Works great!

Using this as a second (back up) battery. It works great and lasts about 4 hours on a setting of 2 liters per minute. With the second battery we can be out and about for about 8 hours now!!!

Customer service is the best!!

My Mother traveled out of the country to visit me and one of her batteries was dead and I needed to replace it asap. Sam not only made sure he did all he could do to ensure we received it before we traveled. Im so grateful that it all worked out. I would highly recommend using Oxygen Support anytime in the future. Thanks again Sam!!
