This bag looks as tough as old boots!! It will probably last until I retire! Loads of room for tools of all types. I've seen other tote type tool bags cheaper than this one, but they didn't look as good quality, and that is why you are paying more than you might otherwise.
These are very good. A bit fiddly to put together, and needed a bit of persuasion to get level. They hold my Tannoy 600a's very well, although I wouldn't want to accidentally knock them! Certainly you don't want to have to pull them apart again once they are put together, so double check your height adjustment before you assemble!
I'm still assessing the sound quality - there is occasionally some rumble, which I need to assess more thoroughly.
