The items came well-packed, clean, and as described. Very few signs of previous use. Top notch. I would certainly buy again from this seller. The only additional feedback is to select a proper shipping option. I will not blame the seller for this. It took more than a month to receive the goods. Next time I will enquire for other options. Great buy!

The part is great, but the level of Customer Service I received is absolutely astonishing. I purchased something similar from another vendor that didn't work, I contacted this vendor by mistake and was immediately offered a replacement and shipping label. A+ on Customer Service This product arrived exactly as specified and fully functional. The overall quality, condition and appearance of the part are all top notch. When looking for parts like this, there is no better value.

A rock solid networking data router!
This is a carrier grade data router. I is a bigger brother to the smaller ER-X series. This one has more CPU, memory and storage. It will run at full gigabit speeds where the ER-X approaches it, but does not quite get there. It has an SFP port for running a fiber link or other data backbone to a switch or other devices. Very flexible, highly adaptable unit. If you just want something that works once setup this is it. This is not a simple networking solution, you need more items to complete a home wifi system with this, and some networking knowledge.This is a carrier grade data router.

The best router for home or small business use.
I matured from consumer network products to small business ones for a simple reason. I can truly set them up and forget about them. They are over-engineered, and the ER-4 is one of them. Very fast and very reliable. Much smaller than a traditional consumer router, and I definitely recommend you wall mount it. Much better. I use the CLI (command line interface) to set it up, but there are wizards in the main browser menu for simple home networks. This is not plug it in and it will start working. You will need to program it, either manually like I did, or via the wizards. Also, this is routing only, not wifi. For that you will need a consumer router which you configure as an access point. or an off the shelf access point. If you don't understand all of this, don't worry. I did not either ...

New route to fast internet without bottlenecks!
Easy to set up through the wizards. Fast and reliable. Only using a small percentage of its capabilities. Dashboard is much more responsive and easier to understand than the old Cisco RV180.

Router for 1GB+ interernet service works properly.
Upgrade from ER-X to provide better CPU. I was able to import my settings easily which made the upgrade simple. Router handles the 1Gb+ internet service without any issues.
