Pros:Very easy to assemble, not that many pieces. Very nice quality, but shorter than I thought it would be (I got 2 for a large dog but it's perfect size for toddlers). Comes with 2 metal pieces to lengthen the gate if your space is wide. I should have paid attention to measurements but overall the gates work fine and keep the dog out of rooms we don't want him in.
Cons:The gate doesn't attach permantly to your space, so you have to tighten 4 large screws (with protective pieces on the ends to keep from marring walls/door jambs)on each corner with a little wrench that comes with the gate. I have some arthritis in my hands/wrists so that was a little difficult for me to do but not impossible or agonizingly painful (took breaks in between but folks without health issues should be able to tighten the screws fairly quickly). Requires 2 hands to open the gate itself,so a busy mom or dad with full hands might get frustrated. Also for the first few days we were tripping over the bar at the bottom of the gate (which holds both sides together, so necessary in the design) but everyone got used to it pretty quickly.
Overall very satisfied with the quality/appearance/efficiency of this product.
