The insert is as advertised but there is no sense paying for the name when the same product (without the bubble) can be had at Harbot Freight for 1/2 the cost.  I use it but in the future I will opt for the aluminum insert +$ or the generic version -$.  The install was easy once I tossed the instructions.  It works, it is well made, the inserts require a dead-blow hammer to remove and I will not purchase another.
