Restock on Mercury Kraken and mouse-pad / mouse help

Hello,

Just registered and looking for some help if possible! I really have an interest in the Mercury line of products and am trying to build a new set-up. If possible, can anyone tell me if they will ever restock it? I don't want to be needy just don't want to wait if it's not gonna restock.

Last thing, I believe I have the Razer Firefly cloth edition gaming mouse pad however I am not sure how to make it change colors. Additionally, I have a mouse (I forget what the name is) however it's started not working. For example, I will charge it for days and then when I try to plug it in the light from the charging station turns on, however, the mouse will not work. I have been fiddling with it for a month or so but eventually gave up and threw in the towel after finding no success. Needed help !

Thanks!
