Review: This device is DANGEROUS and could kill you. PLEASE READ FULL REVIEW... - 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 desertcart. It could cost you your life. It almost cost mine.
Review: my summy - gone over 5 dives professionally and I'll tell you how this product is ●it comes from China. so it's YOUR job to inspect evey mechanic over and test it liking in a bath tub or a pool ●I bought a 75ft extender from the same company and tried to return it for fun and they didn't give money back since they rather have desertcart pay the consumer back ●works amazing and does its purpose. you need to do research on how to scuba and swim properly- I've read some reviews and they seem to be people stressing out from scuba diving and not the actual product "panic attack" ●I've gone in a 245ft quarry and from my pictures I've took i can freely swim and be confident in my gear and my other gear i bought for swimming ●the filter for air is a charcoal filter. you MUST change it every 3 months or the air will get dusty in the tube and make it more clogged up to breath "that filter is on the back strap" ●it stays charged a whole day of diving and they give you a charger and some charcoal filters etc ●it does give a somewhat noticeable pumping noise on top of the machine when drawing in air that's normal. it'll also cut off the pumpin of air into the tube when it has meet a psi so it's not consistent air coming in your mouth which is very NICE ●DONT let others scare you from achieving new experices cause of theirs. I'll tell you I did my own research and studies before I used this gear other than your typical scuba tank. I went diving on my own and I felt safe with this device ●overall buy this if you can meditate your body in water and understand this is a dangerous activity but this product will reassure your safety and experience if you wanna scuba dive!

## Questions & Answers

**Q: If i buy this and it does not work correctly when in the water can i return for a refund ? If nothing is scratched or damaged ?**
A: This company is in China, I didn't find the after-sale service, and I didn't even receive any reply. This is very bad. I purchased a product from this company and I am now facing after sales and refund issues. hope this helps.

**Q: Can this be used with two divers**
A: Not at the same time. About every 30 minutes you have to stop and let the compressor cool down. You could probably set it up for 2 people but I don’t think you’d be very happy.

**Q: how do we contact for warranty issues?**
A: Dear Customer, if there is any problem, you can just send me email through amazon.

**Q: Can the Carbon Filter and Harness be purchased separately?**
A: I haven’t found any place you can buy spare parts and instructions don’t even have an email address

### ⭐⭐⭐⭐ Worth the money!
*by S***S on June 27, 2023*

With four kids and living in Florida there are endless areas to explore. What better way than to get into the water, cool off and see the ocean life. Tried it out in the pool first to get used to it. Very easy to set up and use. We have since used it 3 times out in the ocean and get a lot of people asking what it is. This thing is amazing so far with the use that we have given it. Two things, if using in salt water make sure to rinse it off with fresh water when done. I have a toothbrush I keep with it to scrub the metals when done. Second is there is no carry “bag” or anything to put it in when transporting it. Minor things, this thing is a must if you love being in the water!
