Loving it so far, much quieter than my previous treadmill. Does everything I need and a bit more. I've tried a few of the present programmes and use them as a warm up before doing a long steady pace session. Controls are responsive, and I like that there are speed and incline buttons on the side bars, my previous machine didn't have these. The Heartrate readout from my Polar H10 is a bit all over the place compared to my Polar watch readout, I suspect there is no smoothing. This means that the Heartrate programs are not controlled well. For me this is not a big deal though. The built in speakers work quite well, I alternate between them and my Shokz headphones. The build in 'fan' - nice idea but can barely feel it. Possibly my only issue is the lack of a bottle holder. Overall I would recommend this to anyone wanting a sturdy treadmill and don't need it to fold up. One note of advice - it is HEAVY, 90kg. Getting the huge box from the front door to where it was to be assembled was a challenge and a training exercise in itself :-)
