Great for back decompression and extension. I bought this a while ago when I was having back problems, but stopped using it as I am also prone to occasional vertigo and being upside down was exacerbating it. I've used it maybe 10 times. Was $370 new. Asking $250. Pickup in Morristown or I can meet you halfway. Details here: https://teeter.com/product/dex-ii/
