We have had this tub for a year now. It is simply perfect for us!  It was small enough and lightweight enough to get it up the patio and in place. It has run beautifully, no issues whatsoever. We are in it 4+ times a week, so it has regular use. It does have to run fairly often to raise the temperature in the winter (and we're in N. Florida where the winters are pretty darn mild... but that also means it hardly ever has to run to heat in the summer). Design note some might not like: Only one side is long enough for a person to layout flat.  The other side is more of a relaxed upright position. That works for my husband and I since I like reclining, he likes sitting.
