Great company, product and the technical help people are knowledgeable and super helpful.

Couldn’t use the product due to age of our electric heater however customer service and technical service were awesome.

Shipping was fast and arrived in good condition.

No problem at all and making it the same price as Amazon including shipping makes me buy it directly from sinope as it's better to not give all the money to Amazon.

Received it soon after ordering, great service!
