We bought ours at Target. We used it for about a month and then stashed it in the basement. I never felt it got hot enought to do anything. THe package directions also said that anything you put in it had to be completly dry before running the machine, so we ended up letting stuff air dry overnight, intending to run it through a cycle in the GG in the morning...only we always forgot and then had no "Sterilized" neb to do a treatment with. I don't know...some people here love this product, we didn't think it was worth the $$$.
We were told by our clinic that CFF is expected to endorse this product in the next year, but I have yet to see anything in print that verifys this.
