This does the job it claims it does, conductive adhesive means you can use multiple strips and as long as it overlaps a little it will all be grounded.
That being said there's really not a lot of it, probably enough for one guitar but that's it, it's convenient that you can order this with your guitar and it'll arrive in the same box but you'll be paying a premium for that convenience.
If you're ordering a guitar from Thomann and that's the only guitar you want to shield this is a nice easy option but for my purposes there just wasn't enough.
