Pros: There is no way to describe the pros with this one, I think.
But I will try...
It is an awesome procrastination device.
Nails + hands/stuff/nonstuff = funtime
You keep on smiling with every impression you make
Everyone will think you are super awesome for having one of these, especially if they had one as a kid

Cons: It's way too small, you can squeeze a hand in with some effort, but still it is too small.
The build quality feels bad, but after all there aren't many other ways to build this kind of thing, is there?
As with all other toys of this sort, you can spend valuable time not doing anything but play with this thing
Still, my main consideration is the size

Other Thoughts: There should be an assortment of different sizes (and perhaps shapes?) to choose from.
I'd love one the size of i.e an A4 paper

Bottomline: Great toy
Great timewaster
Not great build quality
Too small, way too small
Awesome value for money
Just another addition to my collection of time wasters :D

Pros: I've been looking for this toy for the longest time, and I wasn't surprised when I found it on DX, since DX seems to have everything. The toy itself is quite a lot of fun to play with, and it is very classic. I got it as a gift for someone who told me that they missed this in their childhood, and I can see why. The simplicity of this toy totally takes me back, and I could not help playing with it myself when I first got it!

Cons: The surface of the glass was very scratched already when I received mine in the mail, even though DX packaged it with styrofoam between the nails and the glass display thing. Also, some of the nails seem a little harder to press in than others, making it a little difficult to play with at times. One of the biggest cons in my opinion was the fact that this version of the toy was so small, although I guess it's to be expected. Any bigger and it would be hard to ship, as well as being too heavy and space-hogging. Although really, with the small surface area, there are not many objects you can press with this, mainly just part of your hand or whatnot...

Other Thoughts: I think the only reason I got this was because I knew someone who wanted it so much. Other than that, it really isn't that great of an item, as it takes up space and is really quite impractical. Although props to DX for having it, it really made my friend's day!

Bottomline: If you don't have a great reason for buying this, like someone you know specifically mentioned wanting it, there's really no reason to buy this object. However, if you were in my position, this item is great!

Pros: This is an awesome toy/gift! I had this when i was a kid in the 1980's. This is neat because it shows the exact shape of any object put up to it. Great build quality! Well constructed!

Cons: The price is high in my opinion. I ordered 1 because i had to give it as a gift. But i don't think ill order again at this high of a price.

Other Thoughts:

Bottomline: Overall a great product , ive seen similar objects in the local stores , but instead of the original metal pegs , they have plastic , they work horrible and jam up. You need the metal pegs like this product , so they have enough weight to go back in place when you flip this thing over to reset it!

Pros: Funny and artistic ! It is great to decorate its office, its room or to make a little original gift.

Cons: Build quality isn't very good ; sometimes the pins are getting trough and they so don't clone the shape. That's the only build quality problem.

Other Thoughts: No other thoughts, I said all I wanted to but I can't send my review because I didn't wrote enough characters... Please, dicrease or delete this limit, I don't want to say anything just for having the correct number of characters...

Bottomline: great deal ; and for this price, the build quality problem isn't really one.
