The ESPN Enforcer Air Hockey Table is a great looking table with plenty of great graphics that make you want to play it. It is 7 ft. long, which is a good size for 2 or 4 players. The biggest problem with the table, is that the scorer rarely works (about 20% of the time), which makes the perceived value diminish. Even the blower motor hum could be overlooked if the scorer worked. Sadly, I would not recommend this table to anyone until this problem is resolved. The blower runs on AC. The scorer requires 4 AA batteries.
