My Alliance 850 treadmill lasted 16 years and thousands of miles
I purchased my Alliance 850 treadmill from PPE IN 1/2001. I was having back surgery and was told I would need to walk a lot to get back in shape.
Well I walked a average on 20-25 miles per week for 4-5 months a year. When it's nice out I walk outside. Due to back and neck issues I can't run
So I walk a lot. There where some days I would go for 2 hours at 4mph.
The last couple of years the treadmill started to show its age. It just died last week, started to smoke after a 90 minute walk.
I would purchase the same model if it was still made. I don't need fansy features just speed and vertical adjustment.
Hope this helps
