Hey gents and gals, today I have a class about the basics of first aid emergency & CPR. My certificate was expired and..well..need it for my job, lol. Went with this one, perfect for cold weather. Although it's not powerful enough to break through today's Quebec temperature of -15°C (~8°F), i'll keep it quiet since i'll be in close proximity of people all day long. Good day to you all!😎
