Assembly of this product was very simple. The directions were clear and consise. It took about 5 minutes to get it together. All you really have to do is put the wheels on and go. Without reading the directions on how to use it we were able to easily figure out all the functions of the stroller. It has a simple twist function on the handle to collapse the stroller. It is really a one handed system to collapse the stroller. When putting the base in for the car seat the directions were once again clear on what to do and what not to do. Once the base is in your car you place the seat in and you hear a loud click to know that it is in. To adjust the seat to the proper level is easy because of the blue and orange dial on the side of the car seat. Just get it to where all you see is blue and you are ready to go. We have a small Toyota Corolla and the seat fits if you move the front seat up a little. We also have a Tundra and it fits perfectly in there. Our baby seems comfortable in the seat and the stroller provides a smooth ride. The neutral colors of green tan and brown make it perfect for a girl or boy. The only negatives that I can find with it is like all stroller systems if you have a small car it can take up a lot of space. I would suggest getting a second base for the car seat so you can easily transfer the seat from one car to another. The additional base is $39.99. This is our first child so simplicity and safety are tops when we look for a product and this met all of our expectations. Hope this helps in making your decision.
