Top critical review
Excellent when working. Good range and dual band wifi. Poor support for 3G/4G USB mobile devices.Documentation not good.

I have had this for a couple of days and have by no means tested everything but I will update this review as I go along.
The model I received was the TL-WR902AC(EU) Ver 1.0.
There are other versions out there.
Also, this model has a recent firmware update available from the tp-link UK website which I have applied.
The first thing to do is check that the built in Wifi networks have a password.
Set the switch to ETH and switch it on. Don't plug it into a network.
When the unit is ready, use a tablet or laptop to visit the WR902 admin page tplinkwifi.net and login.
Check the Wifi settings and make sure both the 2.4G and 5G networks have a secure password set. If not, add one.
I didn't do this and just plugged it into the home network.
The WR902 promptly created 2 completely open unprotected Wifi access points to my home network. :( :(
The wifi range of the WR902 is surprisingly good even though it has no external aerial. However, the unit has to be powered externally (there are no batteries) although it can be powered from a USB port (on your laptop, or car socket for example) so you don't require a mains socket. There was no manual provided. Just a quick guide. I did find a bigger manual on the USA TP-Link website (but not on the UK one). The documentation is not good and neither is the support website. If things don't work as expected, you can spend a lot of time tinkering trying to make it work.
ETH switch setting:
Wifi access to an existing (wired) network. Plug the WR902 into a handy RJ45 ethernet port on the network and switch on. After a couple of minutes the WR902 should provide 2.4G and 5G wifi access to the network. This works flawlessly. As long as the WR902 can get an IP address from the network there is no more to do. If the local network requires the WR902 to have a fixed IP address, you can use the WR902 admin page to enter it.
Wifi access to 3G/4G mobile network. Instead of plugging the WR902 into an existing network, you can plug in a USB mobile dongle. However, the WR902 is very choosy about which USB mobile dongles it will talk to. It doesn't recognise my Vodafone K5160 4G dongle and it doesn't like my old K3520 3G dongle either. Luckily it likes a K4201 3G dongle. The WR902 takes a few minutes to recognise and connect to the internet via the dongle AND you will probably have to do some configuratoin via the WR902 admin pages to make it a plug and play process but it can be done.
