Review on KuWFi Hotspot Partner Wireless Universal by Major Callaham

I like the compact size and affordable price of this device, but there are clearly some quality control and design issues: 1. Right out of the box, the battery looks completely dead. The device only turns on when it's plugged in, and (oddly) the battery gauge shows a bar or two when I plug in the device with the battery removed. (?!?) However, when the battery is inserted and the power cord is connected, the battery indicator goes out and the battery does not charge an iota; In other words, the battery is useless and the device is not portable at all.2. Also, this device seems to only work with extremely outdated full-size SIM cards; It refuses to recognize my data-only microsim (even with an "augment"/adapter) so I can't even test the signal quality and/or range of this device to consider a possible item replacement. returns to Revain for a refund.
