The stamp on this is nice to use but as soon as I put it in place, the color bleeds into the surrounding pores. It doesn't stay the shape it's supposed to unfortunately. Great concept but definitely need to tweak the formula of the liquid.

I like the fact that the music is battery powered! No winding like the old days! Also, you can put music on an SD card and play it in addition to what comes preloaded. Looking forward to using it!

Ex Input:
Right size, very sturdy. My only complaint is that the included anchors and screws were not enough for all the brackets in the package. I was only sent enough for two brackets. So if you buy these planning to use more than two of the brackets, you'll need to get more anchors and screws separately.
