In this article I take a look at the LLANO F15 which is a device designed to serve two purposes: acting as a rugged storage case for your memory cards and functioning as a high-speed card reader.

Keep in mind that LLANO sent me this unit to try out at no cost to make a video on, based on my collaboration terms. This means they have no say in the contents of the video or this article, and they were not allowed to preview anything before publication. I make these website articles as an added bonus to people that prefer written versions of my videos.

Unboxing and Accessories
This is a convenient way to store your Micro SD and standard SD memory cards while maintaining the ability to connect them to phones or computers via USB-C or USB-A ports if you use the included adapter.
In the box, we have the device itself along with a carabiner that you can attach to the stretchy loop on the top. It includes a separate USB-C to USB-A adapter, which is useful for legacy ports though I noticed speed issues with the adapter on my PC. They also provide two additional weather resistance gaskets. This is a nice inclusion; if the current gasket breaks, you have replacements to ensure the IP54 rating remains intact.
IP54 Rating: The "IP" stands for Ingress Protection. The first digit "5" indicates protection against dust (limited ingress, no harmful deposits). The second digit "4" indicates protection against water splashes from all directions. It does not mean the device is fully waterproof or submersible. (Source: Generated by Gemini Pro)
Design and Build
On the exterior, the device features a silicone cover that comes in two separate pieces. You can remove this cover if you prefer a smaller footprint, though obviously, you lose the grip and drop protection the silicone provides.

Underneath the silicone is the main plastic housing. There is a transparent window on the bottom piece of the plastic cover. This allows you to see if memory cards are stored inside without opening it, though this window is only on one side. The plastic cover is symmetric in shape, so you can install it in either direction depending on your preference.
Also integrated into the device is a rubber or silicone strap that is stretchy, along with the carabiner. One design critique I have is regarding the USB adapter. It would have been nice if they integrated the USB-C to USB-A adapter into the device for storage, but I do not see a way to do that, so you will have to carry it separately.
Interior Storage and Features
Looking at the inside, we have space for four standard SD cards as well as eight Micro SD cards. Cards fit on both sides.

Included with the device is a small metal tool that you can use with most phones to open the SIM or Micro SD card tray.

For whatever reason, they did not use the grippy material in all of the memory card slots. If you try to store really thin memory cards, they might not stay seated securely. Although the exterior case will keep them in there so it's not really a big issue if you are careful.
Connectivity and Performance
The device features the LLANO logo on the top, which says "Card Reader 4.0." Around that logo, there is a green light that acts as a status indicator when you are connected to a phone or computer.

On the side, you will find the two ports for reading memory cards. There is a standard SD port that supports UHS-II and a Micro SD port. I have no way of verifying if the micro SD card is UHS-II or not because I don't have any of those type of memory cards.

UHS-II: Ultra High Speed Phase II. This is an SD card standard that uses a second row of pins on the back of the card to achieve significantly faster transfer speeds (theoretically up to 312 MB/s) compared to UHS-I (which caps out around 104 MB/s). You need a compatible UHS-II reader to see these speed benefits. (Source: Generated by Gemini Pro)
Speed Testing on a PC
I tested a UHS-II card in the standard SD card slot connected directly to a computer via the built-in USB-C cable. It ran around 140 MB/s to 150 MB/s maximum. The card I was using is a 64GB Lexar Professional 1000x v60 SDXC UHS-II memory card.

This confirms that UHS-II does work, as these speeds are well above the UHS-I limit. However, when I used the included USB-C to USB-A adapter on my computer, the speeds were running pretty slow. I am not sure if it is the adapter itself or just how my computer interacts with those specific ports, but it is something to note.
Dual Card Functionality
You are able to simultaneously transfer files from both memory cards at the same time. This could be a nice convenience feature depending on your needs.

When accessing both cards at once, the speeds dropped to about 50 MB/s per card slot. It seems to throttle down when splitting the bandwidth. However, once one transfer finished, the speed of the remaining transfer jumped back up to that 150 MB/s range because I was using that Lexar UHS-II card.
Mobile Phone Use
I connected a phone to this device without issue. Both ports were accessible at the same time, allowing for easy file management on mobile.

Obviously, compatibility will depend on your specific phone, but USB-C functionality is generally consistent these days with what used to be called "OTG" functionality.
Conclusion
I can see myself using this for photography or videography outings. It keeps cards ready to go and provides an easy way to offload footage to a phone or computer. Having the SIM tool available (even if it is loose) is handy if I need to swap cards in a phone on the go.
The IP54 rating makes it a safer bet in rainy conditions compared to standard, non-water-resistant card wallets.

Overall, it is a cool multi-functional device for memory card management, storage, and reading.
