This product is really good quality, the inside has different compartments rather than being one space for all your stuff, so functionality is great, the strap is like a belt so it can be adjusted, you get what you paid for, however, after roughly a couple months of use, on of the buttons came lose and fell off, for context the bag shuts only with two magnetic buttons and maybe it was just my bag itself, especially since the other one is perfectly fine but it seemed to not be fitted on correctly, now I'm no tailor but it was held with two metal prongs that must bee stuck into the bag but it still works fine anyway since the other button is fine, but even without buttons it would be fine anyway, all in all, great product and definitely worth my money
