After 4 months I finally received my hot tub. The exterior is bubbled out like a soft pool full of water. I’m not sure if you can see the defects in the photos. The tub heated up to temperature in two days. The jets are not very strong but the lounger is nice and the multicolor lights are pretty at night. 
I am not sure about the sides bubbled out for long term use, but no one has contacted me to see if the tub arrived safely without any problems. The delivery guys were nice and it arrived on a pallet wrapped up. I cannot order more filters because they are out of stock. I’m at 5050 on my review. Defective but it is working and after 4 back surgeries I don’t want to wait for another hot tub ever again. 
If the tub wasn’t bulging all around and I didn’t have to wait so long my review would probably be more positive.
