I am really happy I bought this for my laundry room, which leads out to the garage.  It does require two people at different times.  Everything did line up and I was careful to make sure they did. The 3 boxes arrived, no damage, but are very heavy.  We removed all the parts, one box at a time, instead of moving the whole box.  The only issue I had (why I gave it 4 stars), the backing for the middle cabinet did not have guide holes.  I had to match up the measurements from the other two cabinets so I didn’t miss while hammering it on. I did request a new back thinking it would have guide holes but it came without them also. Bummer! We did not rush putting these together.  So I cannot gauge how long it took us.  All in all, these cabinets are perfect for what I need them for!!
