TOP - absolutely brilliant! Recommended !!!

I have the set - despite many negative criticism on the net - for the third birthday
bought our son. The handling is very easy.
Small cock counterclockwise turn up, invert air balloon over the valve,
Lightly press the valve down, already the balloon is filled with helium.
Make knots, tie belt off and already the balloon pass is completed.
The balloons included in the delivery (15 pieces) are very colorful, large and especially
the helium is sufficient for more than these 15 balloons !!! Have additional 28 smaller balloons
filled with the bottle.
The balloons float included in the set for more than 15 hours !!!! still properly,
the small fell off after about 4-6 hours.
After the ceremony, we let the balloons rise into the sky, and this worked over
satisfactory after many hours floating time in the house.

My conclusion: Original use supplied balloons. Absolutely great product!
