I found the younger ones really liked this especially in the sun.
great service and very fast... i will make new deliveries of this company later thank you!
It is my first experience with Grand Illusions and they proved to be a top notch company. They sent me an extra Spiraculum free of charge, without even asking them to do such a thing. It greatly proves their business ethics: customer satisfaction their utmost strategy.
The connectors on the blue tube that came with it were not ideally sized for each other, so it is quite difficult to connect and disconnect them.
Love it. I am "amazing my friends" and am continuing astonished myself.
I was especially pleased with Mr Ball's personal service in checking to ensure that this item was of a specific size and colour.I've now bought 6 of them!
I have high respect for Grand Illusions. They answered all my questions and even sent me a few replacement parts free of charge. Buy without fear :-)
