After testing the KuWFi 4G LTE Router for several weeks, I've got some mixed feelings about this device. Let me break it down for you.

The Good: For the price, this router delivers decent performance when it works properly. Setup is straightforward - just pop in your SIM card and you're good to go (most of the time). I used it with an AT&T SIM and got speeds around 80/40 Mbps in Toronto, which is perfectly adequate for basic browsing and streaming.

The Bad: The connection drops are REAL. Like many other reviewers experienced, I faced frequent disconnections - sometimes for seconds, sometimes for minutes. This happened across multiple carriers (though AT&T seemed most stable). The non-detachable antennas limit your options to boost weak signals.

Pro Tip: Don't use hotspot plans! Make sure you're using a DATA plan instead. Also beware - some carriers like Cricket may disable your service if they detect this router.

Final Verdict: If you need an affordable backup internet solution and have a compatible carrier (AT&T worked best in my tests), this might work. But if reliability is crucial, you might want to invest in a more premium option like Netgear's offerings.
