Found the Powerbreather, very straight forward to use, with good instructions…
Wish I had of ordered the longer extensions as well though..Overall, excellent..

Product arrived packed securely as described.

Perfect when you have some issues with your neck. Just lay in a still position and swim along.

i am pleased with the product

I had been doing extremely high intensity indoor bicycle spin works out burning 750+ calories in 40 minutes for years when I hurt my back and could no longer spin.
My go to solution had always been to swim with a buoy between my legs and do a traditional stroke, thus kind of dragging my legs behind me and it would over a period of several weeks, start to separate my spin and an elevate the pinched sciatic nerve.
The issue was I could only swim about 20 lengths of the pool before I would run out of breath and have to stop.
I tried 3 other traditional brand snorkels and found that each one of the mouth pieces would start leaking when I subconsciously started stressing/exserting myself or pushing hard off the walls.
I was lucky enough to see someone in the pool with a powerbreather and though I was surprised with the cost, decided if It could take away my pain sooner rather than later it was worth it.
I was immediately able to swim 50 lengths of the pool and stopped only because I ran out of time.
I now swim 100 lengths of the pool, without stopping, pushing off the wall as hard as any competitive swimmer with zero to very minimal mouthpiece water leaks.
This piece of equipment is a game changer!
The people at Freediver Shop have been quick to replace any parts I may have lost.
I highly recommend purchasing the Powerbreather Speed Vent Easy S for pool lap swimming.

Great product does exactly what it said it would do. Ship on time and in perfect condition. Really enjoy using it at its allowing me to swim longer and develop my stroke

with double tub: much more air, no problems with breathing at high speed. Takes a bit of time to get used to... Don't try breathing very sharp and quick - slow and easy is the much better way. Great breather!!!

Simple and intuitive to use.
I swim laps for 45 minutes with no problem breathing.
Definitely an improvement on a regular snorkel in terms of re-inhaling CO2.

Although it took a while, now I feeling very good using my Powerbreather. Thanks
