Inversion Table for Back Pain Does It Actually Work

I have been seeing a lot of ads for inversion tables lately and they claim to help with spinal decompression and disc issues. I have some chronic lower back tightness from years of heavy lifting and I am wondering if this is a worthwhile investment. Has anyone here actually used one for a long period?

Does it provide real relief or is it just a temporary stretch? I have heard that it can be dangerous if you have high blood pressure or other health issues. I am also worried about it being just another piece of equipment that takes up space in my garage.

If you have an inversion table which brand did you go with? I see the Teeter ones everywhere but they are quite pricey. Are the cheaper alternatives just as good or is the build quality a major factor for safety? I would love to hear some real world feedback.
