FEEDING DIRECTIONS

Layers - Feed Manna Pro® Oyster Shell to layers free choice in a separate feeder, or add 1 pound to 20 pounds of layer feed. Pullets - Provide Manna Pro® Oyster Shell to pullets starting at 18 weeks of age and continue feeding through the entire lay period. WARNING:  Do not offer any feed that is spoiled, moldy, rodent-or insect-infested, or abnormal in appearance or odor, as it may cause illness or death. *OYSTER SHELL USAGE FOR CORN BURNING STOVES: Oyster Shell is recommended by some corn-burning stove manufacturers as an additive to promote clean burning, especially when the corn fuel is high in starch.  Please consult your stove's manual to see if Oyster Shell is recommended for your stove and follow the manufacturer's directions for use precisely. Burning Oyster Shell is NOT a substitute for daily cleaning of your corn-burning stove.  Regular chimney inspections are always recommended.  Oyster Shell does not take the place of inspection and professional cleaning of your chimney.  For improved safety and home heating efficiency, it is recommended that all chimneys and vented appliances be inspected every year by a certified chimney sweep.

Does everything, super portable, robust construction
This is a super useful hub. I also used the Anker 341 7-in-1 hub for years, and it was very reliable for every feature, and the 555 8-in-1 looks to be of the same quality. The ethernet adapter is a great addition, and it works right away at 1G speeds on Linux 6.18 and even Android 16. I upgraded from the 341 to use this to connect to and configure devices from my desktop without having to drop my normal ethernet connection, and it is fantastic for that. It's a real swiss army hub, perfect travel size, and incredibly handy.

Great as long as you know its limitations; runs warm; monitor settings may need to be changed
I reluctantly gave up MagSafe and joined the USB-C future when my employer issued me a new 2019 16" MacBook Pro. Searching for a way to connect my various peripherals I settled on this hub as a reasonable way to connect a 4K display, pass power from the laptop charger (albeit not the full 96W; macOS reports 79W after hub losses—good enough most of the time), connect 1GigE, and provide a few spare USB ports and occasionally-used SD card slots. I've learned a few things: A port that looks like USB-C does not pass video unless it is a "Thunderbolt" port (look for the lightning bolt logo, apparently); connecting a USB-C-to-mini-DisplayPort adapter to the USB-C port on this hub did not allow my monitor to work. Lesson learned. The HDMI port did work, and did pass 4K@60Hz, but only after I adjusted my monitor settings. At first I was convinced either my HDMI cable or this hub were defective, because macOS would only allow me to select 4K@30Hz. I have an LG 4K display, and from reading forums, one must enable 60Hz in the on-screen display menu before the monitor will tell the computer it is capable of displaying 60Hz video. For my monitor, that meant changing "Ratio" in "Quick Settings" to "Original" (it defaulted to "Wide", with a separate configuration for each port), as well as turning on "HDMI ULTRA HD Deep Color" from "Picture" -> "Picture Adjust." After I changed those two settings, 60Hz was not available until I unplugged the HDMI cable from the hub and plugged it in again. After that I had buttery smooth 4K video at 60Hz. The hub works as advertised, at least for my configuration. The 1GigE port works well, and is equivalent to a direct USB-C to Ethernet adapter I tried. It does run warm to the touch as other reviewers have reported. That's not problematic, but I'd prefer it pass the missing 17W to the laptop rather than dissipate it as heat. Time will tell how well the hub holds up, but for now I'm happy. In summary: if you have a new Mac this hub will likely work for you, though you may need to adjust your monitor settings.

Older flash drives might not work.
Port labels are too faint to read easily and the PD out port isn't labelled (I suppose they thought it was obvious since it has a fixed cable). The USB ports are speedy except it won't recognize any of my several SanDisk Cruzer Glides. Others flash drives work okay. Works great as an iPhone USB C to TV HDMI converter.

Perfect, affordable solution for a second home-office setup
I work from home and occasionally like to office out of a different area of the house, but I didn't want to tear down my entire main rig just to move to another room. I picked this up as a secondary docking station for a more casual monitor setup, and it works perfectly for my needs. Setup & Performance: I have this hooked up to my work laptop and two monitors via HDMI. One thing to keep in mind: you’ll need to provide your own USB-C cable and power brick to juice it up. Just make sure you’re using a high-quality charging block to ensure the dock gets consistent power for all your peripherals. The Value: Compared to the price of a name-brand Dell docking station, the value here is incredible. While the more expensive docks might offer a few extra bells and whistles, this is exactly what I needed without the hefty price tag. Pros: Simple Setup: Very straightforward to get running. Dual Monitor Support: Handles two HDMI monitors with no issues. Compact: Great for a secondary or portable "mini" workstation. Bottom Line: If you’re looking for an easy, inexpensive way to run dual monitors from your laptop in another part of the house, this is the way to go. Great performance for the price!

Works well but pay attention **REVISED**
The device has worked well for me. However potential buyers should note that the 2nd USB C port is reserved for power input from a separately purchased power supply. So the device provides only a single USB C port for attaching devices. I use the device on power from my own computer. So undocking my computer requires some careful steps in the correct sequence: (1) eject all external drives; (2) power down the external display; (3) unplug Anker from computer; (4) remove power from the computer. The device comes at a great price, though, so excellent value. *REVISION* After four months of use, the HDMI port seemed to fail--the monitor was indicating that it was not connected. I wrote to Anker support and received a reply within two hours. The reply told me how to reset the docking station. It worked. Kudoes to Anker Support!
