It's ok. I have two actually. Some of them have poor latches. Some have slightly bigger necks making it hard to get a good seal. the screen is good for beginning but I moved to using foil on it. The screen corrodes pretty quickly. The personal wind cover is great but obviously get very hot and hard to manage while lit without really good and solid tongs. don't latch it while lit. It's nearly impossible to unlatch while hot. the latch is great for traveling though. I may take the poorer of my two apart if it ever fails and see about using the wind cover portion on my small funnel.
