i can be excessively critical of products and as always your milage may vary but for my own personal use I have created a rating scale for products I review.
1- I want both my money and the time I spent using this product back. It should never be used and if I encounter another in my collection it goes to the trash bin.
2- The product is nothing special but not horrible. I would use it again or give it away if I got it as a free sample.
3-The product is nice enough but I would not repurchase because I have many better options. May be better suited for others
4-I really like this and would likely repurchase if I do not find something better.
5-I love this product and it has become a staple in my collection.
So now you know what the numbers mean!
