We love this product! Before installing it outside, we used a permanent marker to write the size on each pole. Now, each pole has an embossed size mark on it, but marking them made it easier to see and much more efficient to assemble.Inside the _loo, we placed an outdoor carpet under our patio furniture and strapped sandbags to the bottom to keep the winds from blowing it about. The sun does an awesome job of heating it up in the daytime, but on cloudy days or evenings, we use a portable heater with a heavy duty extension cord to keep it warm. Cannot say enough good things about this.
