Welcome to our forum.
I agree .....Your sales person may be over stating something to make it seem a bit more easy ...for most people 3 to 4 times is more the norm and at times can be more than that ....this regardless of what brand of spa you own....
Chas, from reading your posts and respecting your opinions on most issues you address, I am shocked you lost a sale over that, with someone you knew??? LOL
I was bummed, to say the least.
