Leawell Spinal Decompression Belt Improve Spine Alignment Reduce Back Pain Decompression Back Belt with Auto Pump to Easily Inflate CE (25''~40'') A

the product is useless - i tried to tighten it up and still did not get any feeling . The pump itself is worthless and slow. If you take your finger off the button - it goes dead & once re-pressed, it deflates to zero before going up to a feeling-less "30" .Just avoid it
