Unfortunately, the respirator is difficult to use. It is not a single piece but is divided into two parts, resulting in the bottom part constantly rotating in relation to the top.

After a dive, I declare myself disappointed.
The snorkel leaks water from the valve every time you take a deep breath.
As a result, you end up breathing in seawater.
I only used it twice and it's going to be thrown away.
A friend of mine had the same one and the valve broke after a few dives (I thought he was just unlucky)
