Personally, before I purchase anything, I make sure that I read the reviews first to make sure that I will be getting the value for my money.
Just like when I was looking for my coffee maker, I checked out different coffee machine reviews first before deciding on one. So when I bought it I knew what I was getting and in that note I knew what I was not getting also.
The great thing about coffee machine reviews is it comes from real people who have tried out the product. Unlike when it is the manufacturer who promotes their own coffee machine. There is a difference between a testimonial from a person versus product promotion.
And just like what they did when I bought the my coffee maker, I paid it forward by doing my very own review on it also so other people will learn from my experience as well.
