I had a bit of difficulty getting used to the large card size. The card stock doesn't seem to have increased in scale with the cards, so it feels a bit flimsy at first, but I believe it makes shuffling easier.
I am a big fan of the illustrations. I have an original Rider-Waite deck and prefer these illustrations in a side by side comparison. The fact that the cards are so large makes everything more visible, and during readings this can bring attention to minute details that you might otherwise have missed on smaller cards.
The backs look great and are reversible which is something I always look for in a deck. I like the surprise of not knowing whether a card will be right side up or upside down, considering how much this can change a reading. I've uploaded a few pictures to show the relative card size and to give an example of how the backs of the cards look. If you have any use for larger cards I highly recommend this deck.
