Pros:I loved the variety of options for the hardware and the price was pretty good for what you get.I also liked the two tool keys included so I don't have to dig mine out.Cons:What I didn't like however was the poor quality thin plastic container that was partially shattered on one corner before it got to me. I taped it back together to make it work, but its not ideal.The latch on it is not too secure so careful where you store it around little ones. Just a heads up.My experience using it:It does do pretty well what it advertises. Not the best quality out there, but it does do the job if you are in a dire circumstance where say a barrel nut is missing from your crib from storage, and exact replacements aren't possible. Just put it in the back or in a hidden spot so I won't notice the replacement parts. I used a single barrel nut and these were a smaller overall diameter than the originals; so it fit well with some wiggle room in the hidden wood slot to receive the bolt. I find that preferable over larger and you need to sand it make it fit I did need to use a screwdriver to help hold it in place for the bolt to go in perfectly since there is a bigger tolerance space which wasn't too difficult. It held on well with the factory bolt I still had, but I did have to thread the bolt a few times outside of the crib first so it would go together more smoothly when I did put it in the wood crib.If you know the exact length of bolts you need and only need one or two I would recommend buying the smaller less variety version of this set. if you aren't sure, this one has you well covered for most circumstances. I bought this one with more options since murphy's law I might need more in the future and its nice to have a large variety of bolts/nuts for any other future projects or jams I find myself needing to fix.
