While the trick and gimmick are very clever, the DVD is one of the worst I have experienced. First, there is only a live demonstration of one of the illusions done with real people.
The deck color change doesn't explain what happens to the red card allowing you to show the backs of all the cards. There is no explanation of why the spectator would turn over his hands after placing the card on his hand. It was obvious that the "non-spectator" knew what to do ahead of time. It seems to me that you would need several gimmicks to perform the variations since you use double stick tape to attach the partial cards to the gimmick. This would mean you have to pull off the old one and replace it with another one each time. Finally I see no explanation at all as to how to use the Inversion Deck.

WHAT YOU GET:

DVD: 5/5
The DVD is really good. It goes over many useful ideas and in depth and is very good quality too. It only has one demonstration of using quadrant in public but that doesn't really matter to me.

Gimmick: 4/5
Good quality gimmick and it will last just make sure you watch the video before trying anything or you might break the gimmick and have to get a new one. The gimmick is versatile and you can pretty much change a deck into anything small! The gimmick isn't "up-to-date" so some people might see the gimmick but if they aren't a bicycle card expert probably not. Keep in mind you will need to buy a lot of different bicycle decks so it's not that good if you live over seas like I do when a normal bicycle deck is $10! YET AGAIN, I could make my own quadrant with a local cheap deck. I gave it 4/5 mostly because it's a good idea and I guess I can put it in this category.

Performance: 5/5
Quadrant is very easy to use and looks really visual, just like in the video. This is what I love about quadrant, the idea is awesome. Just look at how he changes the deck into a mini deck with one hand! It's very easy to do!

CONCLUSION:

Price:
I would tell anyone to add it to there choose 5 list but truth is you could make one for about $6 but it wouldn't last long. You will be using this gimmick a lot but the actual material isn't much, I still think it's worth the money, it's a really good magic trick. Remember, without buying quadrant you can't make your quadrant.

If you get quadrant you won't regret it and you will use it. It also is a good magic trick.

This is top notch magic - I mean, you can't get any better than this! If performed well, you'll be fooling everyone. The trailer video speaks for itself! I would highly recommend this to anyone. Please be aware that a miniature deck does NOT come with the DVD, and you'll also be required to ruin several cards and card boxes to effectively use this item. The instructional DVD is also sub-par in my opinion (as far as the instruction goes), but there are several ideas and thoughts that are shared at the end that make it useful.

So I got this as part of the choose 5 deals... and I have to say I'm a bit disappointed. In the trailer and on the DVD you're taught several ways to use the gimmick for different effects. HOWEVER, you're only given 1 gimmick which is not really practical/enough to have all the different effects set up as it would require changing/altering the gimmick for each different variation.

It is visual, but definitely not worth the money. Better off spending the money on something else to be honest. Also, there is no mention of how to use the Inversion deck that comes with the DVD at all... lol

This is one of the worst purchases I have ever done from here.

The teaching is horrible. Its like the two guys are having too much fun making these videos. Using each other as spectators and smiling in a horrible self-happy way to the camera. Its like they are two childs. They dont teach presentation at all. The routines are just "I can do a cool effect - watch". No stories, no emotions. So bad.

And you need to purchase more than one product to be able to do the tricks on the DVD. Stay away from this product.

David Regal gives Quadrant a really good review in Reel Magic Magazine. I waited a long time to buy Quadrant, and finally made the plunge when my friends here at Penguin had it in the Blizzard Box for half price. I thought that was a great deal. However, a great deal only applies if something is just as advertised, and in my opinion this is not. I know it is not Penguin, but rather the manufacturer of this effect. To start off, the instructions are just "so so." It has the appearance of being thorough, but you still go away to work on this effect only "kind of" knowing what to do, and definitely only getting enough to assemble one gimmick is just enough to get you started. But that's not the worst of it...(and I don't want to totally give the gimmick away) but somewhere down the line someone must have decided to downsize the gimmick, so the size of the gimmick sent, is not the size of the gimmick that is used in the instruction DVD. At least that is the case with the one I received. When you assemble the gimmick and start, as I did, to do the effect and it just doesn't seem to be working right, you will go back to the DVD and you will notice that the surface area on the gimmick they use is substantially larger than what they have sent you. If the smaller one (pair) they send worked good, that would be fine, but they do not. So go back through the instruction on preparing your gimmick and take notice of the size of the surface covered by what they use and the size of the surface covered of what was sent to you. Then you will understand why it doesn't seem to quite work like it seems to for them. If you are adept at making gimmicks, you should be able to get what is needed to make it work right, but the point is you shouldn't have to. Plus, you will have to order and pay for what you will need which will most likely involve additional monetary spending and shipping cost. So with all this said, I think the effect has potential, but I am not happy I didn't receive EXACTLY what is used in the instruction DVD.

Let me start by saying since I first was on penguin, quadrant was a trick I have wanted. It looked cool and very visual and it looked like it would add spice to my card magic. But, NOPE. I will NEVER perform this. First off, the dvd is not good. They miss many things that are very necessary to know. Secondly, you will not, ever, end or begin clean. Never. You start SUPER angle proof and dirty and you end having to hide or ditch the gimmick. Useless!! This also HAS to be an opener effect. No way it could be in the middle of a routine. The reason I gace this two stars instead of one is because the gimmick is sturdy. It won't break with a fair amount of tlc. Oh also WHAT DO YOU DO WITH THE INVERSION DECK?! No explanation on that at all!

Ok i guess, i have been using Rapture and find the handling
and disposal of the secret items are much easier without
setting up magnets.Most of the items on Quadrant can be
performed using the Rapture system and the cost is more
reasonable. the basics of both effects is tha vanishing
of a card box.

I got this first on the second hand market and rigged it up to turn into a mini Tally-Ho blue circle back with a revealed card. I liked it so much I bought a second. With a gimmick this versatile and eye-popping, it's good to have an extra. My 2nd will be set for the inverted box. Absolutely a gimmick I will use often, and I don't use many card gimmicks. Buy 1, or 2 - you will not go wrong with this one.

I PERSONALLY THOUGHT THE EXPLANATIONS WERE A LITTLE ON THE LEAN SIDE. FOR INSTANCE THERE IS NO EXPLANATION ON HOW TO SET UP THE GIMMICK FOR THE SHRINKING DECK EFFECT, FROM WHAT I CAN GATHER YOU WILL NEED TWO MINIATURE DECKS, ONE OF WHICH WILL NEED TO BE BUTCHERED. IT IS SO OFTEN THE CASE WITH A LOT OF THESE GIMMICK TRICKS THAT OTHER THINGS ARE NEEDED, I WISH THEY WOULD TELL YOU WHAT YOU NEED BEFORE HAND TO PERFORM ALL THE EFFECTS. ON THE PLUS SIDE I DO LIKE THIS TRICK AND WOULD RECOMMEND IT AND IF YOU CAN AFFORD IT GET TWO!
