Awesome piece of kit, the closest i have seen to `gym quality` at this price point. The running deck is large, the machine is robust and sturdy, no shakes or wabbles. I have set this up in my garage on carpet, works great. Very easy to build, I did it on my own in about 20 minutes, no issues at all. Obviously it is a heavy bit of kit, so if it is going upstairs etc then you will need a few people to help. My wife and me have both been using it (we have set up our own user profiles) and both love it. The speaker works ok, but dont expect too much, its a speaker in a treadmill, we have an alexa in the garage, so use that or headphones. One thing that wouldd make this better is if there was an option to buy a custom made cover for it - i bought one off Amazon, ut it woukld be a nice touch to have the option to buy one from DKN. Definitely recommend this product.
