Sunny Health & Fitness Force Fitmill Manual Incline Treadmill for Home, 300 Lb. Weight Capacity, Dual Flywheel, SF-T7723

So far so good. Have only used for an hour so far, so this is a preliminary review for the assembly and first use. Assembly wasn't difficult or complicated; the unit itself IS mostly assembled in the box, and it's heavy, so two people should probably assemble it together. I managed solo but it took a lot to muscle the main part out of the box without dropping it. Once I'd gotten all the parts out of the box, assembly wasn't hard. The instructions are kind of the opposite of those infamous, mostly wordless Swedish Furniture Assembly Instructions, in that these may be TOO detailed, but there are diagrams including an exploded diagram showing what is, I believe, each and every single part, most of which are already put together when it arrives. Assembly is mostly pretty self-explanatory, though, and could probably be done by most people who have put a few things like this together, (i.e., assembled any of the aforementioned nordic furnishings,) while only barely glancing at the diagrams. It IS important to observe the repeated instructions NOT to tighten ANY of the screws or bolts until the end, as that will make your life easier and save you time, since some of the parts have loose tolerances and snugging them up before all others are attached may make it harder to assemble everything. Also, another important note is that the plate underneath the belt MUST BE OILED BEFORE USING. Doing this will help extend the life of the belt and make it work properly, and the (very thick) oil is included in a cute little bottle with cap. It's a manual treadmill which means there's no motor, no instruments, no power required, etc., and it works by gravity and an inclined deck. The angle isn't variable, but it doesn't need to be as resistance is varied instead by a control on the left vertical member. Nothing stops one from placing something under either the front or the back, of course, but there's probably no need to do this. I can confirm the SF-T7732's resistance control works well and is highly effective taking the machine from one on which I can walk slowly, to one where I'm either speed-walking or jogging, depending on how far I incline. There's seems to be no meaningful limit to the speed as there's no motor, so how fast you'll go is really a matter of how hard you're willing to push. I heard somewhere that getting the belt started takes some effort, (possibly from the company's own videos,) and I don't know if they haven't oiled the ramp on theirs enough or I've oiled mine too well, but mine requires virtually no effort to start, and works smoothly. I have, thus far, only ONE real complaint: The control cable on mine has a little too much slack where it exits the left upright tube, which allowed it to get caught between a pair of plates, but there doesn't seem to have been any real harm done, so I used a zip-tie to hold it out of the way to avoid problems when raising the deck for storing or lowering it for use. No biggie.

So far it works as it should and seems well built
