Pros: Nice solid item, quality feel. Really bright!

Cons: What isn't obvious from the image photos is that this item has a FLAT bottom, it isn't fully spherical. You can't roll it to get a number, instead you have to bang it, really quite hard to generate a number. Like breaking an egg.
The dice takes about 6-8 seconds to give a number, and is accompanied by sound effects and flashing. Not practical for a whole game really.

Other Thoughts: Mine came with a keyring attached! Also not very roll-friendly.

Bottomline: Great idea, not a great actualisation of it. Might be good for hacking, put the parts in something more rollable, bottom-weight it, cut the circuit that makes for the blinknsoundz so you get tap-number, tap-number.

Pros: It is really more fun to use these electronic dices than old ones!
The sound it makes when going through numbers is awesome!
The LEDs are really bright and it is not heavy.

Cons: The only way to get it working is throwing it on a hard surface like a table, or the floor. Simply shaking won't make it work.
The dice is hard, so eventually it may end up breaking if you throw it a lot.
I'm also afraid the battery won't last long if you use it frequently.

Other Thoughts: Even if it breaks, or battery dies, it is cheaper to buy a new one.

Bottomline: Price is really cheap!
It will certainly make games funnier.

Pros: C'est un dé électronique qui n'est pas un dé! C'est rond et c'est sympa ça change ^-^
En principe il suffit de le faire rouler pour qu'il s'active. Il n'est pas parfaitement rond (il comporte une petite base) donc il s'arrête toujours au bout d'un moment et permet d'être lisible.
Le prix est correct.
It's a dice, but not square!! Jusr roll it and it should gives you a random number.
Price is ok.

Cons: La qualité de fabrication n'est pas transcendante : on voit clairement une rainure de raccordement entre les deux hémisphères composant le dé. Il ne fonctionne qu'un lancer sur deux ou trois, avec un bip-bip/buzzer électronique très irritant non déconnectable. On entends aussi un bruit type ressort mal fixé à l'intérieur. Les chiffres sortis ne sont pas totalement aléatoires (proportion anormalement haute de 6 et faible pour les 4).
Works only 25 to 40% of the time. Typically, you had to roll it twice or three times to get a number. Random number isn't really random 'cos 6 is given too often, and 4 is quite rare.
Build quality isn't awesome but is ok.
The dice make an annoying electronic noise you can't set to off.

Other Thoughts: Il amusera vos amis quelques temps, puis va saouler tout le monde avec son bruit réellement chiant => vous allez vite ressortir votre dé tout con qui lui marche à tous les coups et est davantage garant du hasard recherché.
Should focus the attention for maybe 2 or 3 minutes. Then, you gonna search your regular style dice for more convenient use.

Bottomline: C'est un dé... rond.
It's a dice... but not square!!

Pros: This is a great dice roller. When you shake it, the numbers lights run fast, until it stops on a random number.
As it was already stated, it runs on cheap LR44 button cells.
Features 7 lights to present the 1-6 results to prevent misreadings.
It's very, very bright.
Dice throws have never been so cool.

Cons: I can't think of anything. Great product.

Other Thoughts: I intend to buy more of these die to my friends. And I expect to replace every regular dice to these great electronic die.

Bottomline: The greatest product i've bought on DealExtreme. Totally worth it!
