Good product for the price
I have been using this for more than a week, overall good product. Must but if you want to use with multiple internet connections in one networkPros: extremely easy user interface5x gigabit portsWAN fail and load balancingSmall form factorNo need for omada contollerSetup and forget configurationsCons: don’t use with omada contoller. Horrible placement of options.WAN connection polling time cannot be set in standalone modeSome settings require hard reboot to apply, auto soft reboot not reflecting the settingsThe order of WAN port number is reversed for working order, last WAN is default not the first one

Still relatively new, But does what it says
It perfectly Load Balances Upto 4 ISPs, You can set 3 Fiber Broadbands + 1 4G Router and it will distribute Traffic to all 4 Connections. Does not have a wifi so need a Separate Wifi Router. Its a good alternative to 470 and 480 Series as their Limitation is the Link is only upto 100Mbps. Its pretty common to have 200~300 Mbps Internet Speeds now and some players offering speeds up to 1 Gbps. In that case the 470 and 480 will be a limitation as max speed attainable is 100 Mbps.Installation is straight forward , you need to make sure the DHCP config in your ISP Routers have a Different IP Subnets else There will be a conflict. Rest you can go by Videos and Community Support and Vendor Support is Good1 Downside : When power goes down, it takes up to a minute to start working . On a Good day , you wont know if one of your ISP is down. On worse day, you will see that you need to do a refresh on your browser or wait a few seconds for connection to fail over.EDIT : Some Reviewers are mentioning that this product is available at half the price in Market. So its double the price on Amazon. I would suggest you do your research about the price well before buying. I bought as soon as it launched, so it was expensive for me at ~7K INR

Absolutely wonderful
I have 2 ISP connection at home. So, that when 1 connection goes down or becomes slow, i can continue the office meeting with the other ISP connection. I was switching between them manually. Also, i had configured to have 2 Wifi signals in the house and this was causing wifi interference between the 2 signals in some zones.I am now using this as 2 WAN inputs and 1 LAN output. I have connected a single Wifi router to the LAN and turned off the wifi from the ISP modems. I now have load balancing between the 2 ISP and also get the sum of both bandwidths when needed. It is perfect for WFH.

Excellent
Excellent and good product as promised.

Lo compre porque desde hace tiempo quería tener una opción para conectar dos servicios de internet que tengo para poder tener una opción de failover y encontre esté en varios reviews y sin lugar a dudas me encanto! super buena opción, fácil de instalar, funciona muy bien, hasta ahora creo que fue una gran compra por el precio que tiene! Adicional creo que si se le dedica más tiempo a la configuración se le puede sacar mucha más ventaja

I bought this because I have two ISPs, but very few home wireless routers support this type of configuration since they usually have just one WAN port. The ER605 works as promised for ISP link failover and load balancing – these are the only features I am using. The device was fairly simple to set up, though you should have a basic understanding of networking concepts such as WAN vs. LAN, DHCP ranges, etc. as the user guide is geared toward business and not home users.In my case, the primary ISP is fiber 100Mbs/25Mbps (download/upload) and the secondary ISP is 4G LTE 50Mbps/2Mbps service. So if the primary fails, Internet access is still possible using the LTE configured as failover; when I tested this by pulling the cable for fibre, it was a transparent failover from an end-user perspective. Also, when both ISPs are online, the load balancing feature uses them simultaneously; Speedtest result shows 143Mbps download and 26.3Mbps upload, fairly close to the theoretical maximum of the combined links’ speeds. I can’t comment on the other features in the ER605, and it seems like there are quite a few especially for a network device at this price point, but link failover and link load-balancing work perfectly.A few set-up notes:I kept my existing WiFi router, but its WAN/Internet port now connects to an ER605 port configured as “LAN,” and then the two ISPs each connect to ER605 ports “WAN1 / WAN2.”The device can be used stand-alone without the Omada management software.Check your network devices to ensure you don’t have two giving out IP addresses from the same DHCP range – this can cause routing issues. ER605’s default DHCP client range is 192.168.0.100-199 and can be changed if required.The user guide is available on the TP-Link support page for ER605, but you need to select hardware version 2.6 – it’s not on the 2.0 hardware version page, but the v2.6 guide is essentially the same for both.
