I have this and I have practiced with an array of glasses or various weights... The issue I have is that they all lean very heavily ... almost diagonal to the eye. This make the product unusable. I have tried rotating ... to get different angles but the effect is always the same. I have tried adding liquid to the glass to play a around with its weigh/displacement but I cannot get it work.

I would love for someone to tell me if/what I am doing wrong so that I can come back and edit this review... I so want to like it.

I like this for its ease of use and concealment in close quarters. There is no dialog in the video instructions but Juan goes over everything in great detail.

I find the gimmick to be very clever and easy to manipulate. The packaging and video quality is minimalistic, but suitable. I think the pricing is on the high end but at least it is something that I know I will use.

I think it would have been better if the gimmick was made of aluminum or better yet carbon fiber, but God knows what that would have cost.

If you work bars,or events where they serve drinks this could easily fit into your routine.

It’s always magical to float something. In this case, you can create a wonderful moment, when you choose the well balanced glass. - With a top-heavy glass, it will not work.
