Query: Assembling these things is never easy

However, it wasn't TOO difficult either. I had help from a friend and we knocked it out in about 1-2 hours. It's very quiet, very strong. I have a two car garage with reinforced metal and this product has no problem working it out. The only complaint with it is the automatic light. That light has a mind of its own, sometimes it will work, sometimes it wont. If it doesn't I just hit the manual override button on it, and all is well. I recommend this.
