GOYOJO Mini Scuba Tank & Snorkel Mask Set with Pump, 0.5L Portable Diving Oxygen Cylinder with 5-10 Mins of Underwater Breathing, Full-face Diving Mask, for Pool Training Snorkelers

The media could not be loaded. Shipping was fast and quality packaging kept the items inside free of imperfections. The quality of the materials of the product is nice and sturdy. Comes with easy to follow Instructions for putting this together and filling the tank with air. We were able to have it water ready in less than an hour. The mask has adjustable straps which is great for having multiple people be able to use it. The mask felt secure and comfortable fit. The air tank breathing engaged quickly when submerged in the water and no water leaked in. My husband has a short beard and he had a few drops of water sneak in but understandable for not being clean shaven. Great value for the quality of the items.

This product sucks you have to pump it 10million times and only get 5 breaths

This mini scuba set is so cool, Im a complete noob so I don't know much about scuba diving but always had interest in it and this gives me a reason to go scuba diving. So I used this set three times now and haven't had any issues with recharging the tank, but I have noticed that I have to press really hard on the snorkel to connect fully, I almost feel like Im going to break it before it clicks in and locks. Im not entirely sure if that's normal, or maybe mine might be defected? But its working so no complaints.

I used this last week since my friends and some family wanted to do a snorkel adventure and I didn't have any equipment, and I am honestly amazed at how much it enhanced my time in the water. I have always loved snorkeling but being able to dive deeper with this compact tank made the experience so much better. The mask was super comfortable and the view allowed me to take in all underwater beauty without any distractions, and the anti fog worked like a charm I could enjoy the sights without needing to adjust my mask which made everything feel a thousand percent better and easy to use.

Missing the silicone mouth piece and parts to connect the handle on the pump , so disappointing I left in box until our trip open it up to assemble and found out I’m missing parts

I was shocked by the quality. I really liked how the mask seals up and ease of use. Also has an auto snorkel, when snorkeling uses fresh air and when diving under to get a shell it uses the bottled air.

Although the oxygen cylinder is small, it can support underwater breathing for 5 to 10 minutes in actual use. Of course, the specific time depends on the individual's breathing rate. The matching manual air pump is also very practical. It can be inflated without electricity. Although it takes some strength to pump it, it feels safer. The full-face mask fits well and has a wide field of view. You can see clearly underwater, and breathe smoothly without feeling that your nose is pressed. It is suitable for people who are not used to using traditional breathing tubes. The whole set of equipment is also very portable. It is very convenient to take it out for fun. It is not as heavy and complicated as professional scuba equipment. It should be reminded that this mini oxygen cylinder is not suitable for deep diving. It is only suitable for use in shallow water or swimming pools. It is a good choice as a snorkeling practice or experience tool. It is recommended to try it in shallow water for the first time to get familiar with the breathing rhythm and equipment response.

Ok, so setting my point of view, I am a certified Dive Master I love blowing bubbles these small spare-air style tanks are fun to use and the full face mask is really helpful for some people who took up underwater breathing later in life and have some time to adjust to not breathing in through their noses.The mask fits multiple face sizes well even holds a good seal on my #2 trimmed beard well so that I do not need to use any thing else to help hold the seal.With the dual snorkels it is also just a great snorkel mask.Now to address the title and my only three stars;The hand pump is about useless at least for me a not in horrible shape 202lb 6' male who has seen the 70's. After about 15 minutes of pumping with the hand pump I finally moved the needle. This hand pump will never be used by me again, nice thought but at maybe 1.5hr to fill this tiny bottle for 5-10 minutes of underwater use I would have to take a NAP after filling and before swimming.I do have fill adapters and my own compressor so this is how I fill this bottle.Additionally a shut off valve would be a nice to have so if someone did fill by the included pump (ha) or other method if the purge valve got bumped in your bag or while on the way to the water you did not risk losing all your air would be cool.Overall if you are not filling by hand, this is a great way to experience blowing bubbles.
