I purchased the Advanced Cleansing System about 3 months ago and bought it because it appeared comparable to the Clarisonic system but much less expensive. I liked the Olay system itself - it was gentle on my sensitive skin and gave me a great, clean feeling afterwards. My husband even tried it and fell in love. We kept the handle dry and were careful not to get the battery compartment wet. However, after only about 10 uses, I had to change the batteries. After that, it worked only on occasion, sometimes requiring a few pushes of the start button or a small shake. After approximately 20 uses, it stopped working entirely, despite trying new batteries and leaving the battery compartment open to air out any possible moisture. I'd like to say it was worth the price because of its results on our skin, but I don't believe I can recommend it due to its very poor reliability.
