Query: Not as good since the product changed

Like others have said, sometime in the past year or more, the formula for this product changed, and it's no longer as effective as used to be. The consistency is thinner and the the scrubbing action isn't as intense. For $30 a bottle, it's sadly not worth it. This used to be a great product, but now I will look for a replacement.
