Hello and thank you for your question.We looked for a reliable, safe, scientific fat treatment machine for many years. Everything I looked at had unreliable and erratic data, or was too uncomfortable for the patient or had placement applicators that did not meet most of our patients' requirements(applicators too large or too small or odd shapes, giving contours that were not smooth) or had too many complications, like burns.The only way for you to get a scientifc report is to try and access the complications data from both companies.I do not have that data, and am merely answering from a user perspective, together with the articles I read or am exposed to in my Plastic Surgery world.We have been delighted with CoolSculpting technology and results. Safe, good size and shape applicators, developed in the USA, lots of ongoing development and research. We have recently purchased the newer-developed applicators, which further improve an already excellent product. Less numbness, better shapes, shorter treatment time, almost no reports of abdominal discomfort. To my knowledge, none of the other copies have this. Also, to my knowledge, the safety mechanisms in CoolSculpting are unsurpassed, and the burns reported are from other manufacturers. The price point for us to purchase other machines is much lower. For us, the more expensive machine is worth it.We now have 2 machines and are extremely pleased with the results. Patients who have treatments with other brands report a vastly improved experience, options and result with CoolSculpting.Thanks for your question and wishing you well in your search.
