Its a perfect addition to my kit, I ordered just 1 piece to see if its really functional and loved it, already made an order for more of these

I routinely use many (20+) of these bags for waterproofing electronics that are left outdoors in wet conditions for over six months at a time. This is used as my second of three layers of waterproofing, I have never had these bags leak when my initial waterproofing container has failed (and it has, several times). My first layer is glass/plastic lid food container, glued shut with RTV, Loksak bag is the second layer, pelican 1000 series case is the third layer. I use Olympus silica packs in the pelican case and Ruggard or pelican 40g reusable desiccant packs in the Loksak bag to keep everything crispy dry. Double zippers and thick plastic material definitely gave me confidence in using this, as opposed to some other brands that have failed me in the past. I've been using this setup for a few years now and it has proved very successful.

I've used LokSaks for many years for other purposes. I recently realized they also make great bags for transporting camera gear in wet/dirty conditions, when dehumidifying bodies and lenses after wet exposure (seal gear in a bag with a with a desiccant pack), and they can even be fashioned into a working rain cover with a little creativity and self-adhering Velcro (if one is cost conscious). Align the bag seams vertically, push the lens+hood into the bottom corner tightly and trace the cut line with a Sharpie. Cut the hole, then use Velcro on the outside edge to create an adjustable collar. The 12x24 bags are fine for storage, transport, and drying equipment,
but you really need the 16x24 bags to conveniently fit a large body
and up to a 100-400mm lens plus extender with plenty of room to get your hands in the drooping  “zipper edge” of the cover. The Loksak fabric is durable enough to clamp the lens foot into the
tripod mount over the bag. It's not a custom fit, but you can see ALL camera displays and reach all camera/lens controls. The only real downside is the extra material (which I rolled up and secured with gafftape will create drag if you're working in a high wind environment.

Keeps my large (11x15) Aegis IIIA backpack insert dry year round.

Worked surprisingly well. It kept everything dry in about pool and beach. It is a bit too small for the iPhone 6Plus with slim case, but works fine for the regular 6.

I tested it to depth of 10Ft and it didn't leak.

great bags for portrait orders

In looking around for this product, B & H had it in stock, in the size I wanted and at a great price!

Used for customer photos and displaying of photos to prevent fingerprints.

Does exactly as advertised. I used it successfully for food hangs while backpacking.
