  • R. Seward - It will work for small jobs

    This product works okay for small jobs (probably what it's intended for) like removing adhesive residue from a bumper sticker etc... I found it to work best with a plastic scraper; apply the product then scrap away the residue, and repeat. The product seemed to dry very quickly so you have to work small areas.

  • A. B. Readerson - It would make an already clean floor look dirty.

    This is a bad product. I received this as a gift from my parents who thought it would lighten my cleaning load. I cheerfully read the simple directions and got started. I couldn't help noticing that it required a great deal of effort to "mop" the floor. Also it did not do a very good job vacuuming. I continued thinking maybe It would be worth it, and I could use the workout. My tile floor in the kitchen did not get very clean. The edges were untouched by this cumbersome beast. As for my wood floor - it was left very dull having this thing smear the dirt around. It was exhausting to use and would make an already clean floor look dirty.

  • Djsal - Best FDA approved agent to aid wth hair loss!

    Minoxidil is the single best agent to promote hair loss available in the market that's also FDA approved. Will definitely keep buying more bottles of this as a continuous supply is needed in order to have continuous hair growth. I received this product at a discount in exchange for my honest review. The packaging was very neat and the product arrived in perfect condition.

  • stinkbug - Classic

    Classic board game. My children love board games and my husband and I enjoy getting them ones we enjoyed ourselves as kids. That's just what you are getting the same classic game you remember when you were young.

  • redhead - the best -- at any price

    I've been coloring my hair for many years and have used drugstore brands, mixed my own at wholesale beauty supply outlets, and had my stylist color it. This product and service is the best of all choices. They did an amazing job getting the color right, the product arrives in a solid package exactly when they say it will, and there's no offensive odor. This color has lasted longer than any I've ever used, including salon color. You can select the frequency of new product (number of weeks) and they communicate every step of the way.
