I have had an "invisibelt" forever now.....and it broke and constantly came undone.  So I decided to take the plunge and try something new!  I am glad that I did....I really like this belt.  It doesn't come undone and I love the stretch....my invisibelt had no stretch so I was constantly having to make it bigger or smaller depending on my wardrobe.  Super comfortable and not bulky at all.  I'm pleased with this purchase. .
