The quality of this product is only fair. As other reviewers have noted, there is an obvious seam on the plastic bubbles. Although the shiny, glisteny finish of the bubbles is nice, overall the product has a cheap feel to it. The instructional video is servicable but has some spelling errors in the titles and the production values are poor. This is clearly a toy, not intended for professional use, although I would think it adequate for birthday party performers.This is a fantastic trick with great props- the plastic balls included have an opalescent coating on them that really makes them look like bubbles! The dvd shows you some great effects and they do require a bit of practice to make it look convincing so I wouldn't necessarily recommend this trick for an absolute beginner. With completely empty hands, you blow some bubbles with a bottle of bubble solution. Touch one and it becomes solid! Next, take your solid bubble and cause it to multiply until you have four solid bubbles! A wonderful effect, especially done silently to some ethereal music. Great for close up and stage.Not worth the price as the quality if poor. The seam is visible on the balls and they are very slippery to perform billiard balls with. The Bottle and wand itself are nice for solid bubble production, so for that it may be worth keeping it, but there are cheaper and better products on the market.At the discounted price of £6.84 I couldn't really go wrong with this. I bought it for the effect of changing a real bubble into a solid and that's exactly what it does. It's easy to do with some simple slight of hand. I've been doing the multiplying billiard balls trick for a while and like the idea of using the bubbles instead of the standard red balls.
