Mackie Thump Go Carry Bag

Generally a good bag that protects the speaker, with good manufacturing quality, but there are two issues with it:
-the zippers sometimes get stuck and I have a feeling they are not going to last long.
-the velcros on the side pockets are way too hard in my opinion.
And then there is some weird flap in the bottom inside the bag that I have not figured out what it is for, but it is anyway not causing any problems.
