Pros: Wanted to go with Cherry MX Browns for my latest keyboard, and Newegg was having a sale on the Helios line. Overall, a nice keyboard. Backlight is good, but not as bright as some competing boards.

As the pictures show, you can change the WASD keys or Arrow keys separately from the other backlight options.

Key caps feel nice. No issues with their fit.

Cons: Keyboard has no onboard memory. Every time you boot up, you have to activate the backlight. That's at least once for the main keys, once for the WASD cluster, once for the Arrow keys, and two to three times for the brightness (it defaults to lowest).

That's a lot of key presses just to get the backlight to your favorite settings so keep that in mind.

The Caps Lock, Scroll Lock, and Num Lock all stay lit and have separate lights in the top right. Personally, I prefer the backlight to deactivate when I turn them off, but it's a minor quibble.

Other Thoughts: Knew about the backlight issue from another review, but my work computer stays on 24/7 so it won't be much of an issue for me. It's definitely a cost cutting measure though, since most current backlit keyboards have onboard memory.

Pros: Charges my phone and laptop at the same time with no problem. Very slim design.

Cons: Fan is noisy and constantly runs even with no load. No On/Off switch.

Other Thoughts: Replaced a Duracell 175 with this. The Duracell is actually smaller, but kept kicking off more and more until it became useless. It was quieter though.

We'll have to see on the long term reliability, but so far this is a good deal.
