If, like me, you need a low latency KB for gaming; and the ability to switch to bluetooth to connect to your work laptop - plus you hate wires, love mechanical, low profile, use media keys and want TKL - then yes; absolutely.
Otherwise, no - there are much better options out there. My F4 key backlight has randomly started turning off (not sure if it's software related, but I've raised with Logitech). The KB itself its beautiful to type on but it does sometimes sound "rattly".
The G915 is the only KB that met all my requirements and I'm over the moon with it but it's only worth it if you need all the features.
