Over 4.5 yrs we've had one issue after another. On two occasions circuit boards in the Hydromate needed to be replaced. We have had three issues with leaks where the liner has holes cut-out for the jets. The tub itself expands somewhat over time due to age and weight of the water; however the vinyl liner doesn't expand, causing it to pull away from the jets. Softub Canada has been totally unhelpful - unwilling to honor the warranty, claiming water chemistry issues without even any actual inspection of the tub. However PH, alkalinity and chlorine have always been carefully monitored and maintained. Our original $6000+ purchase (including accessories) is now ready for the landfill.
