Question: who makes it
Document: Have the options for various configurations is like having multiple ladders at your fingertips and having the plates to create a scaffold makes this a must have product.
The ladder performs just as hoped and is surprising strong - stronger than it looks. There is some compromise on the design, compared to the original, but the price more than makes up for that. I did have to contact the seller about a couple minor damages that occurred in shipping, but they were very helpful and gave me a satisfactory resolution. Over-all, I've been very happy with this purchase.
wish I had thought to check first that the rungs do not have any footpad area. They are only about 1&#34; square, which is hard on the foot, unless you have heavy work shoes on. Also, wish it had a small instruction sheet about how to lock/unlock it. I am new to this type of ladder and it took a little to figure this out correctly. That is probably my fault, not looking it over thoroughly enough first before trying to set it up.
this is just what my husband wanted. It came in before they said it would so that was good. I am very pleased and would recommend to all my friends.
plates did not come with it. good for homeowners. not for contractor's. flex's a little to much for comfort when fully extended.
materials seem poor quality from what i expected, although my husband thought it was fine. clips to adjust height are a little bit difficult  to use. overall its ok but expected more for the price.
Works like it is advertised, be careful with fingers when folding an unfolding you could pinched.
Works great especially getting the ladder away from the gutters. As far as the price, it fell right in the range I was going for.
Will get more use of it shortly.
This was a Christmas gift for our son. He is absolutely thrilled. Already is being used when re-arranging hay bales in the stack.
