Portability & Design: The KuWFi L100US is compact and lightweight, making it ideal for travel. However, some users reported difficulty removing the battery cover and criticized the tiny, hard-to-read instructions.

Performance: Works well with compatible SIM cards (e.g., T-Mobile, Movistar) in the US and Europe, offering stable LTE connections. But it failed in Africa and with certain carriers, highlighting compatibility limitations.

Battery Life: Lasts 5-6 hours on a single charge but tends to overheat when left plugged in or stored in confined spaces like a backpack.

Setup & Usability: Easy to set up for most users—insert SIM, power on, and connect. However, some faced connectivity issues (e.g., no data transfer) or struggled with APN settings.

Value for Money: At ~$50, it’s affordable but polarizing. While some praised its functionality for travel, others deemed it unreliable or incompatible with their needs.

Verdict: A decent budget option for US/European travelers with supported carriers, but research compatibility before buying. Not recommended for high-demand usage or regions with unsupported bands.
