A:AnswerIt's as safe as any other heater. Don't leave it for too long at a time. I would consider it a heater more for keeping your hands or feet warm while sitting in one place for awhile. It's not going to warm a large area or warm a smaller area quickly.
A:AnswerI have had it on for 8-12 hours at a time and the unit itself never gets hot to the touch (and never shuts off from overheating). It doesn't have any sort of tip over protection though.
