Works well and great pair up with a cheap 30 day sim
Used it for temporary wifi for IoT devices. Works well and great pair up with a cheap 30 day sim

Good quality & faster than broadband
Easy to setup, boosts the signal well. Literally plug and play. Ran with a smarty sim & speeds are double that of my fixed line broadband for less than half the cost. Kids playing switches online, watching YouTube on tablets whilst adults watched online tv and no buffering or slowing.

4G LTE router
Works great, insert SIM card. Set password and have good wired, and wireless internet through my apartment. Depending on network coverage, of course, but average speeds, for me, of around 50MBps is fine in operation. Has 3 Ethernet ports. Also there is an SD card slot for network file sharing.

Totally Inadequate in Every Important Respect
Avoid this unit like a carnivorous virus. The app frequently can’t see the router when it’s in the same *room, the average speed (with no obstructions) is 6-Mbps or less, and the online setup requires a password which the router will then refuse to accept.A total waste of money and far too much time.

Easy to use
I’ve had an excellent experience using Mercusys Mesh routers for the past 2 years and so when I got the opportunity to get this, I jumped at the chance. As expected, build quality is excellent with 4 external antennas, LAN/WAN ports, Nano sim slot and up to 32 devices can be connected.Setup and installation is a doddle by downloading and connecting via the Mercusys app. The app interface is simple to use and you’ll be connected in minutes.You have the option to use the router hardwired via ethernet cable which will give you speeds of up to 300Mbs, which to be fair will be fine depending on what you use the internet for. I have multiple gaming setups with 1Gbps Broadband, so for me this option wouldn’t be suitable as the speed would be throttled.Where this router comes to it’s own is when your travelling. You can purchase a data sim which slots straight in and instantly you have 4G internet. The whole family can then connect to that one router. 4G router speed is capped at 150Mbs, but that’s still better than most Hotspots and hotel WIFI.If there’s any caveats than it’s that technology is moving on with 5G now pushing on to be the norm, and so would have been nice if it could capture both 4G and 5G. Overall, fantastic quality, performance and value for money.

Great bit of kit.
Excellent bit of kit. Easy to configure using the Mercusys app and combined with a 50gb Lebara sim, a great broadband solution. I named the ssid the same as the existing router that was being removed and all the existing devices connected when the fixed broadband expired.Iâm using it to monitor doorbell cams on a vacant property and when no longer needed there, it will become my broadband backup for home.Would definitely recommend it.

Wow. Just wow.
So, I bought a house – broadband was still working at first, but then suddenly it was cut off. Needing internet asap, I thought I’d buy a cheap sim router and sim card to be able to get back up and running the next day. So I got this super little router and a SMARTY sim card delivered next day. Where I am, I’m able to get over 70Mb/s – I like how it can be placed anywhere in the house to find the best signal. Oddly enough, I’m finding that the best place is actually behind the TV in the downstairs living room! I like how I can plug Ethernet cables directly into it too for my TV and consoles.My only slight gripe is that it doesn’t have rubber feet, so it does slide quite easily. That’s a very small gripe to have though! Otherwise, it’s fantastic – can’t believe how good internet I’ve got for so little money!

Top quality equipment
I’ve had this thing sat outside for the last 6 months and it just keeps going. Easy to configure, loads of customisable options and given the beating it’s getting from me, I’d say it’s pretty well made too

Bought this for daily online teachings I provide. 5 or 6 hours in a row. No cuts, no limit usage, strong signal even though itâs 4G LTE. Works perfectly with a Three SIM card in Ireland (Not SIM Card for phone number, but for broadband usage).The delivery was super fast. Nothing to complain. Excelent product! Thank you!

Not as good as I thought it would be from the advertisement. Keeps randomly dropping the signal. Switching back to my TP link router. Caveat Emptor!
