My wife bought the 100Gal model while I was out of town. The small size and 100# -sq ft load was perfect for the space available on the deck. This is a simple tub with 4 surprisingly powerful jets. The top got real heavy from absorbing water and I replaced it a few years ago. The new style is much better The flow was slowing down and it turned out that pine tree needles can get through the suction screen. The motor assembly is separate and it only took an hour to disassemble and clean out the pump. When it is hot out we spend a lot of time simply standing or sitting on the edge. Great foot massage and the soft bottom is very foot friendly. It is still the original liner and I am surprised it has held up this long. The 120v system makes install easy. I did put in a dedicated 15amp GFI circuit. I would recomend the brand. If I needed to replace this one I would get the next larger (6 ft)unit. There are no seats or fancy lights but it works for us.
