I'd swapped out a bunch of pedals on a huge Diago board in favour of a Mooer GE200 unit having seen a review of it on the wonderful Chords of Orion channel on YouTube and decided that it was the way to go. Oddly enough the retailer I bought the GE200 from didn't stock the gig bag, but Thomann did and supplied it at a good price and very quickly, so I was able to add carry it safely to my next rehearsal. The bag itself is well made, takes the GE200 and its power supply cable comfortably and I'm glad I went for this rather than a generic bag or small flight-case-style unit of some sort.
In summary, plenty to like about it, nothing to dislike - zips can often be a weak point on bags but this one is solidly made. If you're lugging a GE200 around, buy one, you won't be disappointed.
