For the price, it is a very nice set. Also very simple (though time consuming) to construct if you follow the directions step by step.
Make sure you have at least one person to help you, and make sure you have: impact wrench with good battery and variety of fittings (screwdrivers, Star...), socket set, set of wrenches or adjustable wrench, flat and Phillips screwdriver, and a rubber mallot.
Very important: each piece of wood has a part number on one end. Before you start putting it together, lay them all out in numerical order so that you can find them without searching. This will save you a whole lot of time and aggravation. Do the same thing with your hardware, and DO NOT take hardware out of the bags until you need it.
For the climbing wall: pay attention an make sure that the holes for the yellow pieces are on the top of each board, and that they are staggered (hole on left, hole on rift, left, right...). Also, note that there are two different kinds of yellow rock pieces. Three go on the bottom three boards, three go on top three boards ( you'll see what I mean).
Construct the center square, and then move/orientate before you attach the picnic table chair, slide, or swing brace.
Instructions are very good, but I would definitely suggest waiting on the picnic table, chair, and boarding/spindles for bottom of main square section until after you finish the roof and get it moved to where it will stay. The picnic table seat is the weakest part of the assemble and could come apart if you move it with this piece attached. Also, you have to screw it in and secure it before you place the boarding/ spindles around the bottom.
