So I just put it on my utility belt using the included pouch and was very comfortable. Overall the build quality is very good but, the battery magazine locking mechanism feels a little cheap. I used this for a wedding shoot with my 580EX II and it's a workhorse ! If you're doing extended shoots with critical shots, I highly recommend this unit."
