The main issue is usually the temperature at the is time of year as we have far less issues when its above 20c, most customers report like leapfrog says some deep puffs but also try leaving the device somewhere warmer around the house you don't want it too warm with the battery in these devices won't work well if they're overheated on the flip side of that the oil won't work well if its too cold, unfortunately this is a big complaint around this time of year and we see a lot of positive results when customers warm before using, we also see people opting for carts which can be heated a lot more without the need to be so cautious although we must add that overheating the carts can lead to leaking.
