I was warned by a local playground company that these sets are cheaply made-- and I should have listened.  While I have to admit that this was significantly cheaper than the options this company recommended, it's clear that I got what I paid for.  The wood seems weak, and while it has served it's purpose, I fear it's getting to a point that my 4 year old might be at risk of breaking it (Unlikely, but it's a lingering fear.)
