While I am not familiar with the Slim Freezer Belt, it cannot match the results of true CoolSculpting by Zeltiq, as performed by a trained professional. First, the temperature of the CoolSculpting applicator is precisely controlled to destroy fat cells without damaging nearby tissues or nerves. I doubt an over-the-counter system can make the same claim. Second, an effective CoolSculpting session is dependent not only on Zeltiq's patented cryolipolysis(TM) technique, but the expertise of the practitioner – who needs to be trained and certified by Zeltiq. CoolSculpting is just what the name implies: Sculpting the body by removing fat. This takes not only a practiced hand, but also knowledge of anatomy and a sense of aesthetics. Save your money by not buying ineffective devices. If budget is a concern, bring up your need for a payment plan when you consult with a board-certified dermatologist about permanently removing fat with CoolSculpting; we are always happy to work with patients to help them achieve their goals within their means.
