Wireles mouse help

Not sure if I'm in the right category

Does anybody know where I can buy a Roccat Pyra Wireless mouse?

I have looked everywhere.I want a wireless mobile mouse with at least a forward and back button that is rechargeable. I already own a Logitech G700s. Its a great mouse but is to big and heavy. I like the Razor Orochi but it is not rechargeable.  The Razor Ouroboros is an option but complete overkill like my G700s. Have tried many cheap rechargeable mice but want something nice and well built now.

If you can help me find this mouse for sale in the USA or know of any alternative mice I might not know about that fit my requirements please let me know.

Small and mobile



back and forward buttons

price doesn't matter


Thanks for your help
