Here are my thoughts...
1- My package did not include instructions, I had to go out of my
way to finally get the link and code to watch the instructional video.
2- The instructions
are in Mandarin (?). There's a translator in the room but it's hard to understand her English. For
$130 they SHOULD have given us a better teaching video, one in ENGLISH. This company spent more time
and money making a cool promo video IN ENGLISH and then give us a crappy instructional video that
was recorded in 720p with terrible audio quality.
3- The trailer shows a ring vanish that
is never discussed on the instructional video. I had to figure that one out on my own and it's not
practical.
4- You can only use a thin ladies ring. The instructions say 3mm but I think
its more like 2mm max. You also need wax to keep the ring in place so you can't hand off the ring
for examination without some residue on it.
5- The appearance is loud. If you want to do
this live you'll need to cough or have loud music in the background maybe.
6- The
appearance doesn't alway work. Ring gets stuck at times.
7 - The box looks and feels
fragile, you have to be really careful with it.
Verdict: Great for social media videos if
you mute them or add music, you might have to do several takes depending on the ring you used and if
it keeps getting stuck. Not so great for live performances. I cannot justify spending $130 for video
magic, others might not mind.
At the end of second instructional video they talk about vanishing the ring. But it's not the main purpose of the gimmick.
About fragility, tons of gimmicks are fragile, but if you take good care of it it should last you a life. I personally don't think this one is that fragile.
About ring's size you're right. They must be thin and they don't mention this in the promo video. But if you perform it with the correct size it won't get stuck as you stated in #6.
All the best!
