Just received my "TaroT 3D" (that's what the box says) and so far love it. I have over twenty tarot decks and this one is definitely unique in many different ways: yes, it is slightly tacky/kitschy on the surface, but gives you that warm feeling that you are looking at something that you have never seen before.
Face and reverse side of the box have edge to edge 3D pictures of Justice and Magician - they look even better than the actual cards (I suspect that having non-3D border on cards spoils the illusion somehow). Cards are big and thick - thickness could be a problem if it was full deck, but since it only contains Major Arcana, no big deal.
You have to experiment with light while examining card images - in poor conditions (such as low light level) the 3D effect may be hard to see clearly. Strong, dispersed light seems to bring out the best of the images. Even with the best light, some cards look better than the others - e.g. Fool and Chariot have slight fuzziness no matter how you look at them, Hermit and Justice always look good. Usually there are two angles (slightly off center) that give you the best viewing experience.
Images are mostly traditional - with exception of Death that follows the pattern of Hierophant. Warning for those offended by nudity - no anatomical details are obscured on Lovers, Devil and Star.
My favorite is Hermit - perfect balance of light and shadow, good composition, nice 3D effect. Star is almost a tie - mainly due to slightly less impressive 3D. Tower is the third - it is very dramatic and quite spectacular in 3D.
Another unique feature of this deck is that traditionally 'scary' cards - Death, Devil, Tower - are not so scary thanks to 3D effect - you just admire technical detail so much that you have no time to think about the meaning of the card. Moon card is actually scarier/creepier thanks to the creature that replaced the crab in the front...
I think it is perfect deck for beginners that are not ready for Minor Arcana yet - it should give them lots of joy. At least some of the cards should be good for meditation - 3D would make it easier to 'enter the picture'. I plan to use this deck as a warm-up during readings for newbies. I usually ask them to pick from the Majors one card they like and one they don't like - those choices can tell a lot about the querent and let me adjust the further reading appropriately.
If you are reading in public environment this deck can give you (for a while) competitive advantage - you will be the guy/gal with 'cool cards'.
To sum up - this deck may not be for everybody, but should be satisfying for most, You should see it personally - no photographic reproduction compares to the real experience.
