I'm thrilled to have found an arm band that fits my huge phone in its giant case. I think you need to order the black one that says "Otterbox" for it to fit. I would have liked a different color but love that it fits. It does look like I have a small television attached to my arm and I can't imagine what my tan will end up looking like, but I'm loving the case. The phone slides in and out of the case easily. I put it in with the top of the phone at the bottom of the case so I can see the screen more easily. The regular band fits my twiggy arms really well but it comes with an extender for the more beefy types. Since my case already has a plastic screen cover, I was worried that adding this layer on top would make the touch screen unresponsive but it works fine. I've only worn it about a dozen times so I can't speak to the durability but it's inexpensive enough to replace when worn or stinky.

Works great for me. Started working out and wanted something that could hold the phone. I started out not needing the extension but now use it, so glad it was there. It does get soaked but dries quick. Figure ill fabreeze it till it gets too carried away then I will try to sink wash it. If it does not work I will order another one. Fits my Note 8 in the case (small profile case) just fine. After first use I can pull the phone right out and the screen picks up my finger through the plastic just fine.

Holds my big phone. It is a little difficult to get on but stays on. The key holder only works well for house keys not one's with fobs attached.

Fits my S9+ even in its Speck case and with zagg screen protector. If having issues with touch, remember to adjust touch sensitivity. On my S9+ had to go into settings and search touch sensitivity and turn on the option to increase it for use with cases and screen protectors... other phones may have similar settings.

Like the fact that touchscreen is still operational thru the plastic cover. Fits my iPhone XR with room to spare, very comfortable on long runs. It's still early but so far no issues with durability

Fits many different arms sizes and because I have skinnier arms it was always a problem, best armband yet!

The Galaxy Note 8 is a huge phone. With the OtterBox Defender, it's even larger. This case can handle it in that case. The touch screen is quite usable while in the case. I don't think an arm band can get much better. Wouldn't mind Velcro to cover the card pocket, though.

A little hard to activate touch screen, but that's probably my tempered glass screen's fault.

New phone, needed new armband. I know some reviewers complain of the arms trap being too small, but they are using the wrong holes, as there are two. One for small, one for medium, and an extra trap for larger. I don't use the key pocket or headphone strap holder, but that might be nice for some people. Pros: Great adjustable arm strap, extra pockets, fits my phone WHILE IN CASE (This was a big deal for me, my Clayco case is slim, and difficult to remove, and I didn't want to fight it every time I wanted to go exercise, and yes it is easy to insert and remove), easy to clean, doesn't hold sweat smells, generous openings for all ports, soft material. Cons: Large phones such as the S8+ make this very bulky on my average arm, tends to slide down a bit (Gel lines for extra grip would be nice, like some strapless bras have).

Love the extra band included to adjust the width (so my husband can use it too). Velcro seems to be holding up. The touch screen is a little harder to use than I hoped but I just set a playlist and keep it moving so it's not that big a deal. You certainly cant "work" from the interior while using this (but who wants to do that anyway?).
