This is an awesome trailer. I was a little unsure about what I would be getting for under $100, but have been blown away with the quality and value of this trailer (or as we call it in our house, "the Green Machine"). I only use it for my 3-year old son, but there is tons of room inside. The padded safety harness is comfortable and keeps him safely in place. The huge windows on this trailer are especially nice because they keep him entertained when we are out exploring. I use it 4-5 times a week to bring him to pre-k and it has held up really well so far.
