I have worn squeem cinchers on and off for over 5 years.  They really do both make you look instantly slimmer and keep your eating in check by being tight.  I love them and combined with healthy eating and exercise you can see yourself reducing into smaller and smaller cinchers and sizes.  The only reason I deducted a star is that they don't hold up long.  Worn daily, I find they start to break down over the course of about 3-4 weeks.  The metal stays bend and eventually break from the inside and eventually end up poking and hurting forcing another purchase.  They are expensive so this is the downside but I keep repurchasing because they work.
