Some light leaks out from the bottom as well.

There's a red ring around the otherwise all-black face of the device, and it illuminates whenever the display is on. The front and sides are coated in a shiny, slippery plastic, while the bottom is matte black. It's shaped like an ovular hockey puck, but is nowhere near as sturdy. Made by Novatel Wireless, the 5510L measures 3.9 by 2.4 by 0.6 inches (HWD) and weighs 3.3 ounces. We still prefer the 4620LE (a new version of the MiFi 4620L ($79.99 at Amazon) (Opens in a new window) with an extended battery) for its better controls and global capabilities, but the 5510L is a better bet if you're looking to manage your data usage. With real-time data usage reporting right on the hotspot's display, you can decide whether you really need to download that huge attachment, or if it can wait until Wi-Fi. The $19.99 Verizon Jetpack 4G LTE Mobile Hotspot MiFi 5510L can't help bring down the cost of data, but it can help control how much you use. But I'd never buy one of my own, for one simple reason: Data is insanely expensive.
