As a yo-yo player, I want something that keeps my yo-yos reasonably accessible while also protecting them from damage as they clunk around with my keys/cell phone/whatever else I keep in my bag. I would say that that is the thing this pack really does well because of the three yo-yo inserts in the main pocket. You can easily bust your throw out when you have some down time without worrying about them clunking around in your bag too much.

On the neutral side, this bag is fairly bulky for a fanny pack. I like this because it allows me to keep all my items comfortably in the main pouch. It seems to be marketed as being "offstring yo-yo friendly" due to its large size. However, once I put all my things in there, there isn't much room left over for offstring yo-yos. The main pouch is large enough to store a small tablet or Nintendo switch, which is nice.

My two main gripes would be the outer pockets and the price. On the front, the outer pockets feel a bit too small to be worth much, storage-wise. They are also a bit difficult to unzip and access. It would have been better to make one large front pocket, or maybe a long thin back pocket with a zipper instead of the mesh backing pockets.

Lastly, the price. Looking at the pictures, it appears that the bag is constructed of higher-quality materials than it actually is. Looking at it in person, it feels a bit basic. It is not horribly bad, it just feels more like something that should cost $40 at the most and not $65.
