Query: Very time-consuming to put together

The quality of the product is ok, but it took a good 2 hours to put together, mainly because the last part was so tricky. The directions were not well-illustrated and the written part was very confusing. I bought the Summer Infant Sure and Secure Double Bedrail, which comes already put together, and it was worth the few dollar difference in price. Safety-wise and sturdiness wise, they seem to be about the same.
