Overall, I am pleased with the product. It is versatile and the type of items you can vanish is not limited by their metallic or magnetic property (like, I believe, the Raven is). Of course, like all vanishers of this type, you have to check your angles and the height of your hands in relation to that of your set-up, but that's a given and with practice anyone can work around that.
This being said, I am not giving this product full marks for several reasons:
First, the given length of the hookup doesn't allow me to set it in the exact same way that the instructions recommend. I would expect that the one used in the instruction video is somewhat looser from many many uses compared to the brand new one I received. I also have to use a different grip on it because if I try to grip it the way it is taught, it is (a) too painful and (b) requires so much finger pressure that I cannot hold my hand in a natural way. Now, to be fair, with practice, these two drawbacks might (or might not) be remedied, but there is no assurance. In other words, the suggested grip might work for some (after all, it is used that way, and efficiently so, in the video for all vanishes) but it might not necessarily work for everyone and you may have to adapt it.
Then, one of the elements in the set up, referred to as a 'stopper', is very 'hit and miss'. In fact, more miss than hit. Without divulging anything, its ultimate role is to allow for an easier and more discreet retrieval of the gimmick, but since most of the time it doesn't work as advertised, I am left having to retrieve the gimmick in a way that is not so discreet after all. In short, I either accept this or I will have to figure out a more efficient replacement for this item, which, frankly, I shouldn't have to do.
Thirdly, the instructions do not cover nor give any advice on vanishing larger items like, say, the small water bottle vanished in the trailer. You would think that if it's in the trailer, it would be mentioned in the instructions, even if it's just a few words, but no. Nothing. Nada. Zilch. It's not that I'm expecting to be spoon fed everything, but my thinking for any product is that if it's in the trailer then it is logical to expect that it would be mentioned in the instructions. By not doing so, the customer is automatically left with a measure of disappointment and that, my friends, is not very professional.
Finally, there is also the fact that one of the several items contained in the package was actually missing from mine and I'm having to chase it up. I don't know what happened behind the scenes but whatever it is, it's not my problem and I shouldn't have to worry about it. So whatever the reason for this omission, it's just not good enough.
Despite all this, I am confident that I will eventually work my way around those few imperfections and be able to use the Gecko Pro to its full potential. It's just a pity that it's not a simple matter of practice.
