This is a good lift for the price and does the job. So far it has lifted my Toyota Tundra without a problem and seems to be made fairly well. It holds the vehicle in a sturdy manner, the lift raises quickly, and doesn't bind or stress at all when a load is placed on it. As others have stated, there are no instructions with this product. In addition, I found that the manufacturer provided no pulley for the opposite side of the single point lock release to change direction and provided no means of securing a pulley to the pillar (no threaded holes, nothing). Fortunately, was able to pick up a pulley and welded it under the locking pawl. Once everything was installed the unit works quite well but be prepared for a project and to make some modifications if you are wanting to buy this product.
