The heater to my masterspa failed at the end of the winter. When I went out to check the water, I discovered that as a result of the failed heater, pipes had frozen and cracked.
Masterspa is replacing the heater under warranty but will not warranty repair the freeze damage resulting from the failed heater. Masterspa's warranty excludes freeze damage. They take the position that the warranty excludes freeze damage, even when caused by the failure of a part which is warrantied.
For a product costing more than $10,000, advertised as the best of the best and intended to be used in the Northeast in cold weather, their approach to customer service is truly appalling. I would never buy their products again.
Reason of review: Warranty issue.
