We went to Handley Page Lab at City University in London to conduct a series of controlled experiments using a wind tunnel on our final production units. Amongst our testing was a top end speed test where we successfully demonstrated Firewinder's performance at winds in excess of 75mph - universally called Hurricane speed. Of course, our tests are well prepared for and our Firewinders are fixed to posts which are bolted to the apparatus... and although we only use the standard bracket mounting system we supply with your Firewinder and as you'll see the Firewinder performs beautifully, we wouldn't recommend anyone else using a Firewinder in such high winds.
