I now own the version made by Tenyo. It is far superior.
The Uday product is not as clear (translucent) as the tenyo product. It also is not as reliable.
Sometimes the Uday product is equal, not this time.

I bought this for 7 dollars and threw my money away. The glass (gimmick) leaks and the liquid won't stay in till you are ready to perform. I may have to do a permanent fix but then I can't wash it out........fooey on this.

Every time I bought the glass it worked fine for a while before breaking down.

Ok here's the deal... we bought like 6 of these in less than a year... Even while
being careful with them they break easily... Plus beware if you use this outdoors as direct sunlight will shine through differently at different parts of the glass if you get what I mean. The glue that keeps the prop together won't last to any abuse (pressure, falling to the ground once...) Very very brittle prop.

So as this prop is fragile you must invest in a carrying box for this prop that prevents any damage AND shock to it (perhaps an oversized box with some foam on the inside)

If it were reliable, since I love the effect, i would recommend it... However since the prop won't last that long without breaking I can't recommend it. If you are ready to buy a whole bunch of them just to be sure to have one spare, perhaps you could do a month of shows before your batch breaks down but that's high maintenance...

I would really like to find a version that doesn't break down as easily but I'm weary of this accessory and for the past years we used gel powder instead of see-thru glasses for disappearing milk.
