"When I get into a Swim Spa, for the first time in 15 years nothing hurts! I can swim for 20-30 minutes with no pain. I have a lot of health issues... 5 knee surgeries, hip surgery and shoulder surgery. Doctor said you need to stop running and start swimming. Every penny I spent on my Swim Spa from Swim Spa Source was worth it. This product can't be beat. This is the Mercedes of swim spas and I hope you get yourself one!"
