Perfect for me and my Bee Plus
This organizer will not be useful for everyone with the Bee. The bag does not sit upright if it's attached to the handlebar -- it falls forward. I have not tried it on the back of the seat yet, but as my baby won't be facing away from me for some time, I do not want the organizer to be that far away from me. I attached it to a side bar that's parallel to the wheels and it works great.
Now on to the utility/functionality of the organizer. If you are looking for something to hold your coffee/soda/etc, get the upholder instead. I do not like diaper bags, so this is perfect for me. My set-up goes like this: Skip Hop portable changing station in the basket and the Bugaboo organizer holds the rest... Tommee Teepee bottle, burp cloth, paci's, extra onesie, soft rattle, my keys and an iPhone. This also attaches to my Bumbleride Queen B.
