I did a quick search on the internet, and I didn't find any reviews of it, but it might be worth having a look yourself for it online. Kickback is also on Joshua Jay's Talk About Tricks set - so if you can find yourself a review on that massive set, maybe try one of those, which may have a brief review of the effect?
Alternatively, your best bet may be to make your way to a brick and mortar shop and ask the magicians there.
