I couldn’t find any reviews on it either, actually. 🙁 That’s usually not a good sign.
How exactly do you envision using the bag?
I find myself needing two bags, really. One for transporting the camera gear; getting the equipment safely on-site; big enough to hold just about all the photography equipment I use regularly; pretty durable so it can get jostled around. Then, a second one for when I’m on-site shooting. If on-site is doing a portrait shoot, I usually don’t need anything more than a pocket to store an extra memory card and battery. If on-site is shooting a wedding, then a holster for keeping a second camera/lens combination on me is what I use. If on-site is a family picnic or a walk in the park, then a very small bag for throwing the camera into when I’m not using it works great (if I bring a bag at all). If on-site is a day hike to the top of a mountain, a camera backpack works great, so it can also store snacks and water, along with a rain jacket and an extra lens or two. If on-site is a multi-day backpacking trip, then a waist bag that I can wear in front while the 80 litre pack is on my back, that’s worked well for me in the past.
So, I guess it kinda depends on how you envision using the bag and if it’s going to be used for transporting equipment or more for on-site handling.
The simplest setup I would recommend would be a big camera backpack (for transporting) and a good holster system (for on-site). The holster system isn’t for everybody, and it does leave equipment unprotected for the most part, but it keeps my hands free while keeping the equipment super handy, ready to be used in a moment’s notice.
The bag you linked to looks like a good option for carrying equipment on-site. The one thing that bothers me about it is that, since it has no waist strap, it will swing around when you bend down (or start running :D). It looks like a good swap-out for a purse, though, so perhaps you’d be used it already and wouldn’t see it as a problem. 🙂
