I personally don't like razer. I tried one of their keyboards and it really wasn't that great. I think i'll go for the g500s
thanks for the fast response and good advice!
Something to note about all logitech products:
you can find product information on a tag near the usb connector. You might want to record this for future reference just in case you have to get a replacement. Logitech's service is very good and they will send a replacement without needing your old mouse.
