Disappointed with the overall quality of this spa.  This spa has a rough finish.  The top edges are too sharp to rest your arms on comfortably .  The water depth is too shallow.  The jets are weak,  I would prefer fewer jets with a stronger flow.  The pump has one speed so the jets are on full bore whenever the heater is on.  The spa seems to be well insulated, once it got up to temp it maintained without being on much.  The access cover is simply screwed on through two layers of the plastic, this will be a problem in future as it is near impossible to use the same holes (forced to make a new hole every time you remove/reinstall the access cover).
