## Description

Product Description

Review: Good bit of kit - Just built my shed...man cave! Was just going to fit a normal static vent,but came across this item instead! Unlike most solar vents this one has a battery back up.runs on solar energy during the day also while recharging the battery.then when sun goes down the battery kicks in running the vent almost constantly.it was easy to install, looks good and works better than I was expecting! Glad I bought and would recommend!
