I have owned mine for over 20 years and it is great. I will say that it has gained weight since I first purchased it. I used to be able to carry it all over the place, but now, since it has gained weight, I no longer move it around as much. The locking mechanism of the ladder is still smooth and works flawlessly. I have been known to leave it outside all summer while working on the deck and it didn't suffer at all. I lubricate the "joints and legs" with Pledge spray furniture polish just like the salesman told me 22 years ago and it still works like new. If you purchase them at a "fair" where they are demonstrating them, you can sometimes get a better deal if you purchase some of the accessory items that are made for the ladder. I purchased mine from a demo booth that was set up across from us at a Home Show. I only made one mistake that day. I only purchased one ladder and all the accessories to go with it. Back then, the sales people didn't want to take the ladders out at the end of the show and would sell them off for cost to other vendors at the shows. I should have purchase a second one that was smaller. I believe that the one that I have is also the Model 22. I would like to have a smaller one for work inside the house. The 22 is difficult to carry up the stairs and round the corner at the top landing without hitting the ceiling. It is worth every penny that my wife paid for it!!!!! /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif
