convenient, the batteries lasted for a year at first, then for about half a year (probably, the battery was better in the kit, some industrial one, not for sale separately, then I bought the same ones like GP, but they don’t live up to a year) The receiver reaches far, on any surfaces works confidently. It works well in Photoshop, before mice often jerked the cursor on the unevenness of the table, this one goes smoothly. Works on any surfaces without jumping the cursor.
