Hanif Saifurrahman 4 This product helps a lot in my daily life as it lets me use my shoes without having to worry for the laces being untied. It can be very easily installed, and even if the left side and the right side of the lace ends up being uneven in length, the attacher that is included with the product can be used to hide that uneven part.However, if you decided to use the attacher than you have to be aware that the attacher do stand out. So, that should be put into consideration. I would like to give it 4.5 stars but since I cannot do so I give it 4 instead.
