[This review was collected as part of a promotion.] First impression, these stands are super heavy duty. Not just strong but super strong. Once the black bar goes into the stand, its like a solid combo of a jack stand. There may not be much to say about a jack stand without sounding like a broken record but here are the observations after a full month of on and off use.
Pros:
1. Super heavy duty and instill confidence to work underneath the vehicle: I have been using these jack stands on and off to work on cars as well as to support a boat for a week. Once the stands are put under the vehicle, no amount of shaking seemed to sway them away. I tried to push from one side of the van just for the sake of it while it was on these jack stands but it held steady. super steady. As long as you stay within the prescribed 3 Ton weight limit on a level surface, you should be good.
2. These are ratcheting stands: What this means is that the black bar can be pulled up to increase the height of the stand just by pulling up without needing to fiddle with pins like in a fixed length increment jack stands. For those that have used a regular jack stand without ratcheting mechanism know how painful it is to adjust length of the stand when underneath the car. This stand has no such problem and ratchets freely and is super easy to use.
3. There is a locking safety pin as an additional safety measure. Although the ratcheting mechanism itself locks the black bar in place after increasing to desired height, the safety pin can be inserted into the triangular pin hole on the side and provides additional assurance that the bar is going to be in its place while you are working underneath or supporting a vehicle while storage.
Cons:
The one and only complaint I found with these is that you can only use them confidently as long as there is a hard and steady(level) surface underneath the stands. The bottom plates below the feet of the stand are average in size not too small but not too large either. They do an excellent job as long as they are on a hard level surface but once you take them into the clay or even gravel or any non concrete ground, they dig into the ground. Even slight digging into the ground can make them unsteady for work underneath.
