Lots of geeks on here will have their own views. I know some swear by their Caci, and others use machines that they love but they're not Caci. I have just bought and trained with the Silhouette Dermalift after reading good feedback on here, and speaking to a friend with a very busy salon who has 2 Dermalift machines. Caci was never an option for me - the price was way too high, and now having done a big promo and sold several courses of facials, my machine is nearly paid for. A lot depends on your area - no-one round here knows what a Caci is, so the brand means nothing to my clients, but they trust that if I say this treatment is great, they'll give it a go! Hope that helps you some!
