Have had it for three weeks - used it about 6 or 7 times. I got it to allow me to walk indoors in cold, rainy, windy (or really just lousy) weather.Easy set-up as all have noted. No assembly, take it out of the box, plug-in and go.My belt has been running true and I don't plan on attempting to fine tune it.Holder works fine for my Kindle Fire - and that was where I had my only problem.I stumbled a couple times when 'swiping' to advance a page on the Kindle.Now, I know why 'Tho$e Other Treadmill$" have the large horizontal arms that are parallel to the treadmill surface.A stumble can put One foot on a stationary surface and the Other on a moving treadmill. Not Good, but maybe being 75 years old had something to do with my problem.Solution #1: Use the clip so that the treadmill stops. OK, but I still stumbled and interrupted my walking.Solution #2: Visit home Depot and get two 48-inch long 1-ince diameter dowels and use them like ski poles. As long as my swiping hand side of the treadmill has a roughly 4-foot side clearance I have been fine.Not really sure why the dowels work so well for me - but "if its stupid and it works, its not stupid".Changes I'd like to see #1 A larger bottle of oil (anybody got a recommendation for replacement - I'm thinking sewing machine oil - if they still make that stuff) #2 A better clamp when adjusting the Bar that hold the controls. #3 A daily/weekly/month total for things like distance/time/speed etc. #4 A handle at the bottom end to give something to hold onto when setting it up and when storing it.Overall A great value: Folds flat and stores against wall. Inexpensive, small(ish), quiet, runs faster than I do - way faster actually.
