I bought this to contain a newly adopted cat and relegate her to only certain parts of the house. My friends own one and said their cats can't or won't jump onto or over the gate because of how tall it is. Well, that might be true, but I never had the chance to figure it out. My cat is very petite and slipped right through the bars. Darnit! Now I have a gate that isn't being used but is brand new. Oh well. 

Assembly is a snap --- super easy to put together if you're not drilling the cups into walls (and just using the rubber stopper mechanisms, which are fine, apparently, for non-stair situations).
