These actually work. Instructions could be better, but once you work them out its ok.

Absolutely love it !!!
Really well made
I made my own DIY Tonal work out system with 2 and an iPad

I own a ZYGO unit which has been the gold standard for audio swimming performance. It has worked great for 3+ years.
I have only had your devise for just a few weeks.. It was easy to set up and has worked great . It is very lite weight and i will see over time how it holds up. If it proves to be durable for a few years , you will have a long term customer

Very impressed with the sound quality. Having Bluetooth and MP3 makes these headphones perfect for both swimming and running. A fraction of the cost of the leading brand and barely a difference. Highly recommend these over the brand. Thanks for a quick delivery too.

This is a great bit of kit for my Triathlon coaching open water swimming, I tested it on one of my athletes, I asked her to just swim until a say stop, when you stop I will see that you understood my massage, the lake is a 550m loop, just to test the distance I asked her to stop swimming when she got to the top of the lake and she did exactly that must have been under 200m I am very happy, she also said she could hear the music I was playing.

I'm a personal trainer and was looking for a portable device as a substitute to ressistance bands. I think I found the perfect device.
Top quality materia.
More than enough ressistance.
You can feel the eccentric phase of the workout. Not easy if you do it the right way.
I highly recommend it to anyone who is seeking for a portable and an effective device for your workout or clients.

The device is well built. Arrived as described.

Great device. Only gripe is the tension chord could be slightly longer for raises etc

Really impressedwith quality.Great to swim with music

Th strap makes it possible to do stnding overhead moves which may not be possible without. It would be nice if one set of straps was included.

I don't like to have to download music into my earbuds, I much prefer streaming. This bundle makes that possible for my swim workouts and I love it! I had tried another brand before and Ryofi is not only more cost effective, but the sound and reception are so much better. I would highly recommend it!

The product is excellent and priced just right!

Amazing little machine truly a portable gym. The concentric and ecentric resistances are tremendous to have. Love it so much purchased a second one! Total gym under 8lbs with all included accessories. Thank you Rayofi keep up the amazing work!
