Title: The ID dimension is incorrect
Review: The design is pretty much standard, as far as post drivers go but if you are considering a purchase you would do well to note the shorter 23" pipe length (many other drivers are 36" long) which corresponds to a shorter max stroke (meaning a lot more pounding might be necessary). However my real gripe with this one is the Inside Diameter that is stated to be 2-7/8". For my particular needs I required at least a 2-3/4" diameter or larger, so this driver should have worked. But it didn't! The true inside diameter is a little less than 2-3/4" which is then made worse by the shape not being fully round, but instead being a bit flatten on the welded side. So the largest diameter I could find was just short of 2-3/4" and in places it was reduced to less than 2-3/8". So beware! if the inside diameter is important for your purposes.
