Puzzle Brain Teaser IQ Toy Keychain

Pros: This is a mini version of a similar product, i used to own the large version and when i saw this i just had to buy one.
Good points is the price! You will literally get hours of 'fun' from this, it took me about 2 days of randomly picking it up and playing with it to finally complete it.
It's one of those things that you are trying really hard and then you fail, you get peed off and say you are never gonna try again, then 10 mins later the temptation creeps up and you are trying again. Definatley addictive but VERY rewarding once you complete it. :D
The build quality inside is fantastic - although it needs to be because a slight imperfection or mould leak in the plastic would make it a lot harder to play.
The plastic is also static free (it would be a nightmare if the ball was sticking to the walls all the time!)

Cons: Due to it's small size, the ball can get stuck sometimes, on the edges or corners of the structure, so it requires a skilled tap to get the little ball rolling again.
I found the metal keychain to be distracting whilst playing (you would not believe how much you need to focus lol) but that was easily removed.
I probably wouldn't attatch this to my keys, ever. But its a cool thing to take around with you to show friends/see them fail at it.

Other: If you feel like doing a very cheap little impulse buy, get this! You will probably forget you ordered it and the day it arrives it will be like a present sent from yourself in the past (it was for me) then you can sit trying to complete it all morning and be late for school/work (like me!) haha
Worth every penny! or cent...

Pros: I really like the look of this - two clear plastic halves, joined together with glue and screws (I have a feeling that screws were used just to enhance the look), with four interlocking peices inside, each of a different colour, that form an elaborate maze to twist and turn a little ball bearing through. Good fun - simple idea - move the ball along the track, twisting and turning as you go - but difficult to solve - you have to focus on it, and think carefully about your next move.

Cons: My main beef with this awesome little puzzle toy is the materials - hard plastic - looks like it will crack if you drpo it, and break if you sit on it. If i'm using something as a keyring, I don't want to have to worry about breaking it.

Other: A great little puzzle toy, simple t pick up, difficult to solve, minimal frustration factor. Just at risk of being broken in your pocket.

Pros: Cheap, or, actually, not so cheap for something useless.
Colorful.

Cons: Too small.
the ball is too small and too light for such a game.
Build quality is so-so and the ball doesn't roll smoothly on the tracks

Other: don't buy, get the bigger one.. unless you just lost your key-chain and this this might be a nice fashion item
There is not much to write about such a small and simple item...

Pros: -small, compact sized, easy to carry -comes in assorted colors -the maze itself is quite difficult, to some maybe stressing, but to me it's quite challenging

Cons: -the build isn't quite solid -i ordered 5 piece of this maze, 1 of the maze track isn't atached well so when i roll the ball, it stuck in the track -the maze is difficult, might be stressing for some

Other: -quite nice to kill some time while hanging around -work best as zipper accesory on your bag
