I’m on an AliExpress kick lately particularly to find the cheapest stuff out there. Haha and yes, you do get what you pay for! I couldn’t however pass up this item when I was scrolling through “ford transit mk8” stuff.

Its a slider bug wall/screen. Description says it fits Sprinter and Transit so I immediately knew I was taking a gamble but at a whopping $25 I was like, what the heck. Well 10 days later it came in and honestly I’m pretty impressed for the money. It rolls up and down, has buckles to hold it up but also has a “permanent” border for 3 of the edges making look better than just sticking up some mesh curtain with magnets! The zippers are a little wimpy (wish it was magnetic like the amazon DIYs) and I’m guessing it’s not as heavy duty as commercial products out there but I was able to install it today using a combo of the included Velcro and also tucking in the rubber door seal. Time will tell but I might just order another for a backup just in case.
