Honestly, I love this treadmill and so glad I bought it. Works great. Quiet. Easy to use. Only reason I'm giving 4 stars instead of 5 is because the manual is not very clear. Its missing some valuable information. And because this treadmill is an offbrand, there aren't many useful YouTube videos on it. For example, the manual doesn't mention or show the power button in the manual where the function chart is. I accidentally stumbled on it when I was looking for the oil lubricant inlet. On that note, the lubricant inlet is not clear in the manual and the pictures are no help. I still don't know where I'm supposed to inject the oil. Also, the emergency stop tab doesn't work. Technically it does, but the magnet that is on the tab isn't attached to the tab. So if you push it down, the machine doesn't turn off because the magnet is still on the machine (see pics I've included) . I will have to super glue the maginet to the tab so that it works as intended. These are all silly issues that should've been caught during quality control before being put on store shelves. So, shame on the company. Also it would be nice if the wheels moved in a way that make it easier to curve around corners. It's a hassle if I need to turn left or right. And the machine is a little heavy so its hard if I'm putting it under the bed (for example) but the wheels don't move that way so I have to actually be strong enough to lift the machine and push it under because I can't roll it under the bed horizontally.
