Fewer turns to disassemble and join bottle to lid, less risk of cross threading, superior to original unit that shipped with concentrator.
Thank you for your review :)
It was good but shiping takes a log time if u guys can be able to send it faster service will be 100%
Thank you for the review! Due to Covid-19 causing extreme demand for oxygen supplies, we are shipping orders as fast as we can, but slower than normal. We quote a 10 business day lead time on Oxygen Concentrators but supplies like filters and tubing typically ships in 2 days or less.
