Works very well, great versatility, but heavy.

This ladder is designed to be as versatile as you could possibly need, allowing you to not only use it as a standard ladder for reaching high places, but also to use it on uneven surfaces or steps, and even to reach second-floor areas or windows.

The major upsides of this ladder are all the major things you would want in a ladder. It’s very sturdy to stand on, with great grips on the feet to keep it from sliding around. It can be adjusted to a variety of angles, including 90 degrees or even 180 degrees to extend it into a taller, double ladder that can reach rooftops or high windows. Because of the strong grips and adjustability, you can set this ladder up in such a way that you can use it on stairs or slopes without any problems. The locking mechanism also ensures that once you set up the ladder, it won’t ever start to change angles or slip, as the lock is extremely secure and easy to adjust once you understand it.

As someone on the heavier side of the scale, this is the first ladder I've felt comfortable standing on without someone holding it, no wobbling and no worries. Would be ideal for someone who uses a ladder for work and works alone.

The downsides to this ladder are not deal breakers for me, but they are still problematic. The locking mechanisms are not well explained at first, and need to be experimented with to really understand. The individual steps are thinner than most ladders, and the ladder itself is very heavy and very large, making it tough to transport around. The major issue for me is the fact that this ladder has no tray of any kind that you can rest tools or small equipment on, such as nails or lightbulbs, forcing you to carry them up with you and hopefully not drop them. Maybe adding a tray top would have made it too hard to have the ladder be fully adjustable like it is? You can hang a bucket or bag on the 'lock' knobs to help you with that, but a tray is always handy too. Love the wheel system to make it a lot easier to move it around.

Overall this ladder is versatile and reliable, with the only downsides being the weight and the lack of a tray to make your work easier. It's definitely worth it for workmen or those who own a house, but for those who use a ladder only occasionally, it's probably a bit overkill unless you have a lot of spare cash.
