I would have easily have given this 4 stars if it had a nicer paint job and was sanded properly. I received this all neatly wrapped in paper and bubble wrap. Couldn't wait to open it..but when I opened it I was surprised by the finish as it was a bit of a rough job. I performed this to my family at a distance, they were suitably amazed but I did keep the blocks moving. Weather I got a bad batch I'm not sure BUT THANKFULLY Penguin of course was there to help! Very happy with their after sales service.
I also deducted a star because the gimmick was a little on the big size and a bit noisy but as another magician pointed out..so long as you twist the blocks around, you can't really pick the size difference and with a bit of music you can deal with the noise issue or alternatively I used my finger to catch the gimmick so it doesn't clunk.

The magic props works well and the instructions are user friendly and easy to understand.

The workmanship on the product is not that great. Very little glue used and seams of the blocks were coming apart. I cannot be bothered to send it back as I have already paid customs on it but will have to do some glueing.
