Got this costume for a friends stag do and it went down a storm with everyone (including strangers). Good quality material and generally well made.
It's worth noting this item requires 4 x AA batteries, and you need a small phillips screw driver to open the battery compartment... good job I checked before the weekend!
Paperwork enclosed said the costume would stay inflated for up to 7 hours. We used Duracel batteries and my friend went limp within 4 hours... still 3 hours 58 mins better than normal though!
Lastly when you put the costume on be sure to tighten all of the draw strings, otherwise it will not inflate fully.
Well worth the money!
