netFiber 9 is a powerful outdoor switch with SFP SFP+ and Gigabit Ethernet. It features a powerful ARM v7 CPU 256 MB of RAM 4x 10G SFP+ ports and an advanced Marvell switch-chip that can handle even the heaviest loads. The Gigabit Ethernet port is not just for management purposes. It has a direct connection to the switch chip – so you can enjoy full gigabit speed. This port also supports PoE-in so you don’t have to rely on the DC jack for powering in tight hard-to-reach spots. There is a console port followed by five regular SFP ports and four SFP+ ports for that sweet 10 Gbps networking. This means there might be quite a lot of wires for you to organize at some point. That’s why Mikrotik designed the case to have some handy little additional features on the bottom of the case to help you keep everything neat and tidy.The sturdy case provides decent protection in dusty environments with occasional splashes of water. Perfect for outdoors with some light coverage – like a roof overhang or a simple cabinet.There is a massive heatsink on the back that serves two purposes. Not only it provides outstanding heat dissipation it also moves the center of mass towards the side with all the mounting options – keeping the board firm and strong upon installation. The package includes metal hose clamps and screws so you can attach the netFiber to a pole wall or mast right away.netFiber 9 is an amazing tool for anyone working with connections over 100 meters while keeping data loss and ping low. Optic fiber can be a great alternative to copper if you are worried about electromagnetic interference or maybe even tampering and eavesdropping. With 10 ports a powerful CPU and a rugged case netFiber 9 is a real bargain that will make your network management so much easier!

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days. Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.
