The O-Puff portable O2 inhaler seems like a really great idea. When I was testing the

product, I did tend to get a little light headed, but I couldn’t tell if it was from the extra

Oxygen or just from slowing down and taking 3-5 deep breaths. I was really looking

forward to feeling invigorated, but it was hard for me to feel anything really. I’m giving

the O-Puff 3 of 5 cannabis leaves because I think it’s a great idea in a thriving market

and I think they are onto something useful here.
