"First, this product is extremely unique. I couldn't find anything like it out there. It may seem pricey, but this is ABSOLUTELY what you should be using for attic storage if your space is insulated. It is dead simple and you will wonder why you paid all this money for it, but the beauty is in the simplicity. I haven't completely finished my install, but I've gotten far enough along to know the pros and cons. On the "pro" side, it is easy to install. It really is one of those "measure twice, cut once" situations though where you spend more time planning out the install than doing it. All of the parts you need are included EXCEPT for the decking itself. They don't include the decking because it is shipped from the UK and that would be ridiculous. I was able to find the appropriate amount of tongue and groove decking at the local home depot for total cost of less than $50 but could probably be even cheaper if you decided to use larger sheets of plywood or something. It seems extremely sturdy once assembled despite the pieces themselves all being extremely light. Shipping was MUCH quicker than originally estimated. As for the cons. This kit is geared toward 24" joists. I (along with many people) have 16" joists, so I ended up spacing the triangle struts with two joists between them, and as such decided that I would stagger the I-beams to distribute the load between the two joists. This was not specified in the instructions or if it was, it wasn't very clear. All in all though, this is a great product. The price might be a little steep but it's likely easier than building it yourself unless you are Norm Abrams and it is truly the right way to do it."
