I ALMOST DROWNED USING THIS PRODUCT. I actually thought I was going pass out and die. I am a very fit 5'11" and 190 pound man. The first couple of times I used this product I was finding myself getting very winded after around 20 minutes of diving in around 10 feet of water. I didn't think much of it at the time and would just swim to shore, catch my breath and go back to diving. On my last dive, I accidentally got disoriented and found myself far from shore, in the middle of the lake. Because of the low airflow output, I was severely out of breath and weak. I honestly wasn't sure if I was going to make it back to shore. I had to spit out the mouthpiece, drop my weight belt and swim back to shore. I barely made it back before I started to pass out from lack of oxygen. I didn't realize just how poor the airflow output is for this product and what effects it does to the body in terms of the hypoxia. After this incident I started doing research and found that similar products have 2 or 3 times the amount of airflow output and that is why they are more expensive. This product is the CHEAPEST for a reason. It has the lowest airflow of ALL other diving ventilators. I've read some of the positive reviews and seems like the only people this product is suitable for is small children, NOT ADULTS! This product is DANGEROUS and SHOULD NOT BE FOR SALE ON AMAZON. It could cost you your life. It almost cost mine.

To be reasonable... these chinese regulators and scuba dive thigs, are not safe at all... my opinion is... even a children is not suited for this kind of product... But is good to know that you are safe and well! You have a big history!
