Avoid Artesian Spas at all costs.
I purchased a 2004 top of the line Piper Glenn. Its product is average to say the least.
Aside from a main control panel malfunctioning twice, a pump going out and all the plastic control knobs discolouring but the warranty is worthless and the company customer service department is deplorable and abusive to the consumer.
I've been trying to get a warranty issue repaired for over a year, the first service rep fixed one problem but caused several others, the second service rep knew nothing about the product, sold me replacement head rests that came from Artesian incomplete and has been paid for them (of course advance payment required) but when I call Artesian I get nothing but abuse.
You're lucky if they ever return a phone call. They don't listen to the consumer, they act as if you know nothing and then hang up on you.
Don't waist your time or money on Artesian. All you're buying is a future nightmare!
