Hi,
This thread is to inform others that the Dyson airstrait does NOT function at higher altitudes. I was not aware of this when purchased, and discovered this after the 30 day return period. Dyson has done nothing to rectify other than offer more products that won’t work at altitude. Buyer beware.
I also couldn’t leave a review, so had to resort to leaving here for others to be made aware of this incredibly frustrating design flaw.
