The 0-3 month guide has improved our quality of life significantly. My 11 week old son sleeps in his cot just by following the settle/resettle guidelines per the program. The guides are full of great information and so easy to follow.
I keep buying this product as my kid is used to of this and it is convenient to carry. But in the last 2.5 years this is my 3rd machine. The other 2 just stopped working suddenly. We use these machines very carefully without any rough handling. Quality can be improved to increase the product life.
