Tell us how you get on if you rent one…I could not find anything more powerful than 2.4 atmos to hire / buy in Uk for domestic use, and although there is anecdotal evidence that the home ones even at 1.5 atmos create some relief the real evidence of benefit for LC seeme to be 4+ atmos like the Israeli one and even they then have extra oxygen variation…far to pricey for many of us sadly!
