Have the True 300 with the orthopedic belt. Had it for 4 years now with no incident. Not a lot of variety on the programs, but it can put out 12mph and still runs like the day we got it. I wouldn’t hesitate to buy another (though this one shows no signs of wearing out).
BTW, I do 75% of my run training indoors, so between my wife and my running, this thing probably has close to 7000 on it and is still going strong.
