Bought the mouse about a month ago and it's absolutely great, can't fault it anywhere!

Very good gaming keyboard and mouse, loving the responsiveness of them and having the mouse wireless and never having to worry about charging is great, charges as you play.

Really good mouse, used a g502 before this and oh what good choice I made !. I buy this mouse for the wireless capability, it's cruel. Works just like a wired mouse, though no cables are in the way. Wireless + + sensor (3360 optical) + Left and right are really comfortable.

Extremely accurate, long-lasting battery, fast charging, and highly customizable.

The Logitech G903 Lightspeed Wireless Gaming Mouse is one of the best mice we have encountered, the price might be high but it's more than worth it.

Smooth and free moving and perfect for all ages

When a company expects you to spend over $150 on a mouse they better provide...

Solid wireless performance; Unique wireless charging; Ambidextrous Design; Good ergonomics; Extensive customization

While the size of the PowerPlay base was a bit small for Danbo, he was blown away by the native battery life that gave him 5 days of battery life at his regular gaming use. Even when he receives a low battery warning, he could finish his game instead of scrambling for the USB cable right away.

I really liked the G903. Its heaviness (and optional weights), the ability to change the DPI with the middle buttons, the customisability allowing for adding/removing the side buttons and being able to set them. I found the battery life was good, too. I bought this to replace a G502 HERO that had a faulty mouse wheel, and it did well for a while. Unfortunately I noticed it started double-clicking and got worse to the point in which it wasn't usable (in and outside of gaming). MightyApe were quick to respond and provided a refund — I might pass on Logitech for a while though after several products have now failed on me early on.

The Logitech G903 Lightspeed remains one of the best wireless gaming mice on the market, though, especially considering its lower price when compared to the Razer. If you’re in the market for a wireless unit for mainstream and competitive gaming then it’s a great option.
