Shipping was great, arrived sooner than expected and no damage at all. We are very impressed to say the least! Instructions are very clear and easy to follow. Jets are very powerful just as full sized hot tubs are. When we first filled it it took a good full 24 hours to heat up to 102. Which is to be expected of a plug and play but we're impressed at how well it does hold heat once it's at the desired temperature.  Overall we're very impressed with our purchase. Friends of ours now might be purchasing the exact same one ever since they tried ours!
