I picked up Hard Times preparing to enjoy it since Charles Dickens is my favorite author. While not going so far to say that I was disappointed,I will say that it was the first Charles Dickens novel that I almost felt like not finishing. Not only is the plot rather humorless, but the characters are charmless and almost uninteresting. If it hadnt been written by Dickens then I may have liked it better but as it was it did not have any of Dickens usual charm and humor.

This product worked for 4-5 times and the rotation stopped working. Batteries run out or lose power after 3-4 uses. I would read reviews before buying another one... I am looking into the Hitachi wand massager now and I believe I will buy it since is a power operated toy and will never run out of power.Not impressed with this product.

I can't believe I wasted my money on this! When I got the product, I had before-hand read some reviews about it falling apart or something. So, before I wasted the sand that came with it and caused a mess, I gently pressed on the wood/base part. It was flimsy, but I didn't think much of it. Then, while just doing a quick look over, I noticed that there was a small disconect between the bottom base and the black lining. This would cause the sand to leak out of the crack! Then, the base fell write off! I noticed that it had very tiny, small metal pieces that had wood from the base around it. I now realize that they probably put the metal into it, painted the top black, then pushed on the base to connect the two parts. The little "stubs" that hold it up have superglue stains from where they glued it to the bottom of the base. How cheap! I really don't know what to do now. I'll probably get my dad to put some nails in it. Really, the Dollar Tree would probably make a better structure!
