Our Verdict

Logitech G915 LIGHTSPEED

Logitech G515 LIGHTSPEED TKL

The Logitech G915 LIGHTSPEED and the Logitech G515 LIGHTSPEED TKL are wireless gaming keyboards with low-profile designs. The G915 is an older, full-size model with dedicated media keys and a volume scroll bar. It also has a row of five dedicated macro keys, but you can't program macros to any other keys. On the other hand, the newer G515 TKL has a more compact 80% form factor. It also has several small improvements, including higher-quality PBT keycaps, pre-lubed switches and stabilizers, and acoustic case materials that make it quieter. Lastly, while it doesn't have dedicated macro keys, you can program macros to any key using the configuration software.
